 Page 4 

 4.2. Calculation of Royalties. Royalties payable by LICENSEE to CMU shall be calculated by LICENSEE each Quarter
based on the number of units of Licensed Products sold by LICENSEE during that Quarter (less the number of returned units, if any) (“Calculated Royalties”). In the event of sales by LICENSEE’s sublicensees, distributors or VARs, the
royalties will be calculated on the number of units of Licensed Products sold by such sublicensees, distributors and VARs as if those sales were made by LICENSEE. The Calculated Royalty shall be equal to {***}, but the Calculated Royalty for each
unit shall in no event exceed {***} of the Net Sales with respect to that unit. In the event LICENSEE is required to make any payments to any third parties in order for it or its sublicensees to practice the Licensed Technology, LICENSEE shall be
permitted to offset {***} of such payments (before similar offsets under the third party agreement) against any Royalties payable by LICENSEE under this Agreement, but such offsets shall not reduce CMU’s Royalties by more than {***}.

  
 4.3. Payments in U.S. Dollars. All payments due under this Agreement
shall be payable in United States dollars. Conversion of foreign currency to U.S. dollars shall be made at the conversion rate existing in the United States (as reported in the Wall Street Journal) on the last working day of the calendar
quarter preceding the applicable Royalty period. Such payments shall be without deduction of exchange, collection, or other charges. If by law, regulation, or fiscal policy of a particular country, conversion into United States dollars or transfer
of funds of a convertible currency to the United States is restricted or forbidden, LICENSEE shall give CMU prompt written notice of such restriction. LICENSEE shall pay any amounts due CMU through whatever lawful methods CMU reasonably designates;
provided, however, that if CMU fails to designate such payment method within thirty (30) days after CMU is notified of the restriction, LICENSEE may deposit such payment in local currency to the credit of CMU in a recognized banking institution
selected by LICENSEE and identified by written notice to CMU, and such deposit shall fulfill all obligations of LICENSEE to CMU with respect to such payment. 
  
 4.4. Payment Terms for Royalties. Royalties shall be payable quarterly on the ninetieth (90) day immediately following the Quarter for which such Royalties
were calculated. Payments of Royalties shall be made promptly by LICENSEE, with no invoicing by CMU to be required. 
  
 4.5. Withholding and Similar Taxes. LICENSEE shall pay all taxes which may be assessed or levied on, or on account of, the Licensed Product made, used or Disposed
of hereunder and all taxes (other than taxes imposed by the United States of America or the Commonwealth of Pennsylvania or jurisdictions within such Commonwealth) levied on or on account of the amounts payable to, or for the account of, CMU under
this Agreement. 
  
 4.6. No Right to Suspend Payments. Notwithstanding the
pendency of any infringement (or other) claim or action by or against LICENSEE, LICENSEE shall have no right to terminate or suspend (or escrow) payment of any amounts required to be paid to CMU pursuant to this Agreement. 
  

	5.	LICENSEE Shares 

  
 5.1. Issuance of Shares to CMU. As a partial royalty for the license rights granted by CMU herein, LICENSEE agrees to the following: within thirty (30) days from the Effective Date, 

  

 Page 5 

 
LICENSEE will execute and deliver to CMU that number of Shares of LICENSEE’s common stock that shall constitute two percent (2%) of the total of
all Shares of LICENSEE’s common stock then outstanding. 
  
 5.2. Prior to the
first of (a) LICENSEE becoming a public company through an IPO or a merger with a dormant or other public company or (b) LICENSEE merging or selling all or substantially all of its assets to another company that is not more than 50% owned
by LICENSEE’s then shareholders (the “Public Company/Sale Date”) CMU shall have preemptive rights with respect to additional issuances of equity securities (or securities convertible or exchangeable into equity securities)
(“Equity Securities”), including without limitation issuances of Equity Securities to LICENSEE employees in exchange for cash, the effect of which will be that CMU shall have the right to subscribe on the same terms for additional Equity
Securities so as to maintain its two percent (2%) equity interest without dilution or diminution. If additional Equity Securities are issued in conjunction with a merger or acquisition, in order for CMU to exercise its preemptive rights, the
valuation of those securities will be made by an independent third party, agreed to in advance by both parties (if no independent third party can be agreed upon by both parties then by an arbitration pursuant to Section 22.) The independent
third party valuation (or arbitration) will be considered final. 
  
 5.3. In any
public offering of securities conducted by LICENSEE, which includes Shares held by LICENSEE’s Shareholders as of the Effective Date, CMU shall be entitled to participate on a pro rata basis to the same extent as such selling Shareholders (or
any permitted transferee of such selling Shareholders) and on terms and conditions no less favorable to CMU than those provided to such selling Shareholders (or such permitted transferee). 
  
 5.4. Prior to the Public Company/Sale Date, CMU shall have the right of co-sale such that, if
another Shareholder desires to sell all or any part of his or its common stock, now owned or hereinafter acquired, and the LICENSEE does not exercise in full a right of first refusal to acquire such stock, any such sale of common stock will be
subject to the following rights of co-sale. CMU shall have the right to sell to the purchaser of the stock, on the same terms and conditions, an amount of Shares equal to the number of Shares of common stock (including Shares of common stock into
which each of the Shareholders may convert any other stock) then owned by CMU equal to (i) the percentage ownership of CMU in the common stock of LICENSEE (including Shares of common stock into which each of the Shareholders may convert any
other securities convertible into common stock) times the number of Shares to be sold or (ii) at the option of CMU, a lesser number of Shares (“Co-Sale Right”). The effect of this Co-Sale Right will be to equate, on a percentage
ownership basis, the number of Shares sold by the selling Shareholder and each of the other Shareholders, which may prevent the selling Shareholder from selling the number of Shares which he or it originally intended to sell. 
  
 5.5. Notwithstanding the foregoing, the provisions of Section 5.4 shall not apply to any
sale by a Shareholder in an underwritten public offering under an effective registration statement under the Securities Act of 1933, as amended.

 7.3. All Royalties payable hereunder which are overdue shall bear interest until paid at a rate equal to the Prime Rate in effect at the date such royalties were due, but
in no event to exceed the maximum rate of interest permitted by applicable law. This provision for interest shall not be construed as a waiver of any rights CMU has as a result of LICENSEE’s failure to make timely payment of any amounts.

such party shall promptly notify the other parties in writing of such infringement and supply the other party with all evidence possessed by the notifying party pertaining to and establishing said infringement. The Inventors will have the first
right, but not the obligation, to bring an infringement action against the alleged infringing party, using counsel reasonably acceptable to Spectral. If the Inventors do not commence an infringement action within thirty (30) days of the date
the Inventors become aware of the alleged infringement, Spectral shall have the right to bring an infringement action against the alleged infringing party. The party conducting the action will have full control over its conduct, including the
settlement thereof; provided, however, that no settlement of an action will be made without the consent of the other party (which consent shall not be unreasonably withheld or delayed) if such settlement would adversely affect such party.

  
 (b) All monies recovered upon the final
judgment or settlement recovered pursuant to this Section 5.3 will be divided among the parties as follows after the party conducting the litigation first receives its legal fees and other third party costs incurred in conducting such
litigation: (i) the Inventors will be entitled to an amount equal to the remaining amount of the final judgment or settlement multiplied by {***}, and (ii) Spectral will be entitled to the balance of the judgment or settlement.

ENDOSCOPIC INVENTION 
  
 IMAGING ELASTIC SCATTERING SPECTROSCOPY 
  
 Inventors; Daniel L. Farkas, PhD; Elliot S. Wachman, PhD; Jill Wachman, MD; Miriam Farkas, MD 
  
 BACKGROUND OF THE INVENTION 
  
 Field of the Invention 
  
 [0001] The present invention is broadly concerned with providing a non-invasive
technique for the early detection of cancer and other abnormal tissue and, more particularly, to the field of imaging elastic scattering spectroscopy (IESS). 
  
 Description of the Background 
  
 [0002] Detecting abnormal tissue early is critical to the successful treatment of disease. Life expectancy of patients with malignancy or cancer, for example, can
increase dramatically when abnormal tissue is identified while still in a pre-malignant state. Such tissue regions, dysplasia and carcinoma in situ being typical examples, are ordinarily detected by surgical biopsy. The removed tissue is sent to a
pathologist, where it is examined under a microscope for the characteristic morphological changes that indicate abnormal cell growth. Upon receiving the pathology report, the physician can then decide whether further removal of the tissue is
indicated. 
  
 [0003] This method of treatment has a number of serious
drawbacks. For example, only a limited number of regions can be biopsied, with the choice of region determined only by its gross appearance in the eyes of the physician. It is therefore quite likely that a problem area, particularly one in an early
stage of abnormality, may be missed completely. Another serious drawback of this method of treatment is that since the identification of abnormality must await the pathology report, surgical removal of the abnormal tissue often must be performed
during a separate procedure (and sometimes even by successive iterations), thereby increasing risk to the patient, and inconvenience and cost for both the patient and the physician. 
  
 [0004] Within the last decade or so, a number of all-optical techniques for identifying abnormal tissue have been developed in an
attempt to avoid these problems. These approaches have the potential for allowing problem sites to be detected over a large area sensitively and quickly, without having to rely on the subjective judgment of the physician. In addition, because
suspicious areas can be identified during the initial examination, diseased tissue can be removed immediately, and completeness of the excision assessed by prompt reimaging of the area in question. 
  
 [0005] The most developed of these optical techniques makes use of differences in the
spectra of fluorescence exhibited by normal and abnormal tissue. This fluorescence is ordinarily excited by laser illumination, and can be either intrinsic or extrinsic. Although numerous groups are working on the development of fluorescence-based
systems for cancer diagnosis, to date only one device has reached the commercial market. The LIFE scope, manufactured by Xillix Inc. and marketed by Olympus, Inc., uses ultraviolet laser light to excite tissue autofluorescence through a
bronchoscope. It is presently being used by approximately 50 groups worldwide with a cost of upwards of $200,000 per unit. Although this device provides much greater sensitivity than standard white-light bronchoscopy, single procedures can be very
time consuming. Even experienced surgeons often require 45 minutes to perform one examination which would take only 3 minutes using standard bronchoscopy equipment. The use of the LIFE scope is not only quite draining for the patient and physician,
but also limits greatly the number of patients that can be seen, thereby substantially increasing procedure cost. 
  
 [0006] Other groups have used Raman signals to identify abnormal tissue, however these signals are extremely weak, and it may be difficult to implement as a
practical clinical tool. 
  
 [0007] A third approach, elastic scattering
spectroscopy (ESS), illuminates the sample, and looks at the spectral content of the light scattered from tissue right beneath the surface by using a point probe in contact with the tissue surface. This method has the capability of detecting
disorganized epithelial orientation and architecture, morphological changes in epithelial surface texture and thickness, cell crowding, enlargement and hyperchromicity of cell nuclei, increased concentration of metabolic organelles, and the presence
of abnormal protein packages. ESS has been used to study the skin, the eyes, the bladder, the prostate and many different regions of the gastrointestinal tract. In one study, ESS was used to differentiate neoplastic from non-neoplastic tissue and
adenomatous polyps from hyperplasic polyps in the colon with a predictive accuracy of ~85%. In another study ESS was used to detect 

  

 Page 37 

 
bladder cancer with a sensitivity of 100% and a specificity of 97%. Preliminary tests of this technique in the lower GI tract demonstrated the ability of
differentiating between dysplasia, adenoma/adenocarcinoma, and normal mucosa with a sensitivity of 100% and a specificity of 98%. Studies in the skin have demonstrated a sensitivity of 90.3% and a specificity of 77.4% for distinguishing primary
melanomas from benign nevi. Over a decade of clinical trials with this instrument in a variety of organ systems has shown that these spectra can provide a sensitivity means of detecting even early abnormal tissue. At present, however, this method is
capable of providing single point measurements only, thereby making it inappropriate for routine clinical use. 
  
 [0008] Therefore, there is a need in the art for a system for detecting ESS signals in a full imaging mode which can be equally applicable to imaging endoscopically and imaging externally for routine clinical
use. 
  
 SUMMARY OF THE PRESENT INVENTION 
  
 [0009] One aspect of the present invention is a method of generating data which
comprises illuminating a target with polarized light and serially imaging the target at both parallel and perpendicular polarizations for each of a plurality of different wavelengths. The serially imaging may include: illuminating the target with a
wavelength-tunable light source; illuminating the target with a broadband light source in series with a wavelength-tunable filter; illuminating the target with a broadband light source and detecting reflected light with a detector whose wavelength
acceptance can be chosen by interposing chromatic filters in the light path; or illuminating the target with a broadband light source and detecting reflected light with a wavelength-tunable filter in series with a detector. 
  
 [0010] Another aspect of the present invention is a method of generating data which
comprises illuminating a target with polarized light, serially imaging the target at both parallel and perpendicular polarizations for each of a plurality of different wavelengths and determining range information indicative of a distance to the
target. Again, the serially imaging may include: illuminating the target with a wavelength-tunable light source; illuminating the target with a broadband light source in series with a wavelength-tunable filter; illuminating the target with a
broadband light source and detecting reflected light with a detector whose wavelength acceptance can be chosen by interposing chromatic filters in the light path or illuminating the target with a broadband light source and detecting reflected light
with a wavelength-tunable filter in series with a detector. Additionally, determining range information may be accomplished optically, sonically and/or mechanically. Further, determining range information may be accomplished by illuminating a spot
of the target with a collimated beam of known diameter and degree of collimation, recording the size of the illuminated spot reflected from the target, and calculating the distance to the target using the size of the illuminated spot and the known
diameter and degree of collimation of the beam. 
  
 [0011] Another aspect
of the present invention is screening for abnormal cells and is comprised of illuminating a target with polarized light, serially producing a series of images of the target at both parallel and perpendicular polarizations for each of a plurality of
different wavelengths, determining a distance to the target, and analyzing the series of images based on the distance to identify abnormal cells. The analysis may include an analysis based on Mie theory mathematics. 
  
 [0012] The present invention is also directed to an apparatus comprising a light
source for generating polarized light. Means are provided to convey the polarized light to a target. A collector receives light reflected from the target. A detector is responsive to the collector for generating images at both parallel and
perpendicular polarizations for each of a plurality of wavelengths. A range finder detects a distance to the target. The apparatus is under the control of control electronics and may be configured to image areas on the surface of the body, or
configured so as to be inserted into various body cavities. Typically, the apparatus would be used in conjunction with an analyzer for analyzing the images for evidence of abnormal cells. 
  
 [0013] To enable the generation of images at a plurality of wavelengths, either the source of light or the detector is wavelength
tunable. The polarizers may include any of a variety of known polarizing devices including, but not limited to a polarizing sheet, a polarizing beamsplitter, or a polarizing-preserving fiber. The range finder may be an optical, acoustical and/or
mechanical device. 
  
 [0014] The present invention provides a non-invasive
technique for the early detection of cancer and other abnormal tissue. The present invention allows for detecting ESS signals in a full imaging mode which can be equally applicable to imaging endoscopically and imaging externally for routine
clinical use.

 DETAILED DESCRIPTION OF THE INVENTION 
  
 [0023] One embodiment of an apparatus 10 constructed according to the teachings of the present invention and useful for screening for abnormal cells is illustrated in FIG. 1. In FIG. 1, a patient 12 is
positioned on an examining table 14. A target 16 is examined by apparatus 10 as will be described in detail below. Those of ordinary skill in the art will recognize that target 16 is meant to be exemplary and not limiting. 
  
 [0024] Most internal and external surfaces of the body are covered with a layer of
cells known as the epithelium. One of the more common types of epithelial tissue is known as the “columnar epithelium”, in which a single layer of epithelial cells lies on top of the thicker sub-mucosal layer. In such a case, the
epithelial nuclei can be considered as scattering spheres embedded in a surrounding uniform medium of different optical composition. 
  
 [0025] The way that light scatters in such a situation depends upon a number of factors: scattering angle, sphere size, wavelength and polarization of the light
being scattered, as well as the optical properties of the spheres and surrounding medium. The mathematics used to describe this scattering is known as the Mie theory. Hence, if the wavelengths and polarization of the illumination light, the
detection angle, and the optical properties of the tissue are know, the Mie theory can be used to calculate the size of the nuclear spheres responsible for the observed scatter. If a camera is used to produce images of the light reflected from the
target 16, then an analysis of the images will result in a map of nuclear size at each point in the tissue imaged. This is the basis of imaging elastic scattering spectroscopy (IESS). 
  
 [0026] The apparatus 10 shown if FIG. 1 is illustrated in greater detail in FIG. 2. In FIG. 2, a light source 20 is used to generate
polarized light. The light source 20 may be comprised of a filament 22 or other source of light. Filament 22 may be a tunable light source or a broadband light source. Should filament 22 be a tunable light source, it is preferably capable of rapidly
switching between wavelengths. Should filament 22 be a broadband light source, a tunable filter 24 may optionally be used in series with filament 22 to provide light at discrete wavelengths. Tunable filter 24 should be a device that is capable of
rapidly switching between wavelengths, such as an acousto-optic tunable filter (AOTF) or monochromator. The light 29 from light source 20 exists device 10 through an illumination port 30 for illuminating the target 16. The light source 20 is
directly in line with illumination port 30, or fiber optics may be used to convey light to the illumination port 30. Additionally, a polarizer 26 may be included in light source 20 within the light path to polarize the light. Polarizer 26 could be
any device that polarizes light, for example, a polarizing sheet, a polarizing beamsplitter, a polarizing-preserving fiber, among others. Those of ordinary skill in the art will recognize that polarizer 26 may be any polarizing element known in the
art. The light source is under the control of control electronics 28. 
  
 [0027] Target 16 may be any tissue, including external tissue, such as the skin, or internal tissue such as those accessible endoscopically or otherwise, as will be described below. The light 29 is polarized at this point and may be
serially tuned through a plurality of wavelengths by the filter 24. Alternatively, and as will become apparent, the light could remain broadband, with the tuning occurring on the detection side of apparatus 10. 
  
 [0028] Light 32 reflected from target 16 is received by an imaging port 34. A
collector, or series of collection components, 36 is responsive to the light 32 collected at the imaging port 34. Collection components 36 may include polarization filters 38 and imaging optics 40. An imaging detector 42 is responsive to the
collector 36 for generating images at both parallel and perpendicular polarizations for each of a plurality of wavelengths. If filament 22 is a broadband light source, and light source 20 does not include tunable filter 24, collection components 36
may contain a tunable filter 24 to provide for spectral discrimination. Tunable filter 24 should be a device that is capable of rapidly switching between wavelengths, such as an acousto-optic tunable filter (AOTF) or monochromator The 

  

 Page 39 

 
imaging detector 42 is under the control of control electronics 28 and, when collector 36 contains a tunable filter, the collector 36 will also be under the
control of control electronics 28. 
  
 [0029] Apparatus 10 includes a range
finder 44 for detecting the distance between a range finding port 45 and target 16. Ranger finder 44 may be implemented using any known form of optical, acoustical (sonic) or mechanical range finding device. Range finder 44 is under the control of
control electronics 28 and will produce range information for each target 16. 
  
 [0030] An analyzer 46, which may be integral with apparatus 10 or remote from apparatus 10, is responsive to the images and the range information. Based on the range information, the images are analyzed to identify abnormal cells
using the aforementioned Mie theory. 
  
 [0031] A method of operating the
apparatus 10 of the present invention is illustrated in FIG. 3. In FIG. 3, at step 50, polarized light 29 is used to illuminate target 16. At step 52, light reflected from the target is collected. At step 54 the collected light is used to serially
create images at both parallel and perpendicular polarizations at a plurality of wavelengths. The resulting set of images provides elastic scattering spectra at each imaged point. 
  
 [0032] Step 50 may include illuminating the target with a tunable light source or a broadband light source in series with a tunable
filter. Alternatively, step 50 may include illuminating the target with a broadband light source and step 54 may include detecting reflected light with a tunable detector or with a tunable filter in series with a detector. 
  
 [0033] At step 56 range information indicative of the distance to the target, e.g. the
distance between the target and the range finding port 45, is generated. The range information may be generated optically, sonically, or mechanically. Although FIG. 3 illustrates the range finding step after steps 50, 52 and 54, the range finding
operation can be performed either before or in parallel with steps 50, 52 and/or 54. 
  
 [0034] Steps 50, 52 and 54 may be referred to as a method of generating data as those steps result in the production of the images needed to screen for abnormal cells. The method of generating data may also include the range finding
operation represented by step 56. 
  
 [0035] At step 58 the generated
images are analyzed based on the distance information. This analysis may include an analysis based on the Mie theory. The analysis may determine the nuclear size distribution point-by-point throughout the imaged region. Because size information is a
parameter often used by a pathologist when diagnosing biopsied tissue, the analysis results may optionally be pictorially displayed before the physician (with, for example, different sizes depicted in false color), thereby providing a near real-time
assessment of the nature of the tissue being examined. Those of ordinary skill in the art will recognize that the screening for abnormal cells can be done offline. That is, steps 50, 52, 54 and 56 may be performed and the data transmitted to a
remote location for analysis or stored for later analysis. 
  
 [0036] FIG.
4 illustrates another embodiment of the present invention in which the apparatus 10’ is configured for screening for abnormal cells in a body cavity. A portion of the apparatus 10’ may be designed as an imaging probe to be inserted into
and removed from an instrument channel of a conventional endoscope 64, or incorporated as a permanent additional port in a modified endoscope. 
  
 [0037] As shown FIG. 4, light source 20 may be a spectral light source. Light source 20 may be a monochromator (Polychrome IV, Till Photonics, Eugene, OR) or
AOTF-based source (ChromoDynamics, Inc., Lakewood, NJ), fed through a first optical fiber 66 which leads to the distal end of an endoscope probe. First optical fiber 66 provides a means for conveying the polarized light. In an endoscopic embodiment,
fiber optics are the most practical way of conveying the light from the light source. In other embodiments, mirrors, beam splitters, prisms, reflective devices, fiber optics, direct paths and the like may be used as means for conveying. Polarization
of the illumination light may be provided by sheet polarizers (not shown) at the two illumination ports 30 (see FIG. 5A) instead of using polarizer 26 as shown in FIG. 2, or by other means. The single imaging port 34 (see FIG. 5A) has a second
optical path (which may be provided by a pair of optical fibers or a lens system as shown in FIGs. 6A and 6B) responsive thereto to direct the collected light to the collector 36 discussed in detail with FIGS. 6A and 6B. The optical fiber 66 has an
outer diameter and length compatible with insertion down the instrument channel of conventional endoscopes (for many scopes, this necessitates an outer diameter less than 2.0 mm). 
  
 [0038] FIG.5A illustrates range finding port 45. FIGS. 5B and 5C illustrate a simple, inexpensive range finding mechanism useful for
determining the distance between the tissue and probe. Range finding may be implemented using a low-power, infrared laser diode fed fiber-optically into an optical range-finding port at the distal end of the endoscope. The output optic on this port
will collimate this beam as much as possible to insure that the exiting beam has a very low divergence angle. For a given starting beam diameter and degree of collimation, the size of the spot illuminated on the tissue as a proportion of the entire
illuminated field-of-view will vary depending upon the tissue-probe separation, as shown schematically in FIGS. 5B and 5C. At larger separations (as shown in FIG. 5B) the near-collimated range finding laser spot takes up a smaller area of
illuminated field of view than at smaller separations (as shown in FIG. 5C). The laser can then be pulsed on once, or several times, per image set, the size of the reflected spot in the tissue measure, and from this, the tissue-probe distance
calculated. Although this technique 

  

 Page 40 

 
will provide a reasonable determination of distance only in the center of the images field, this should be sufficient for the purposes of the IESS analysis,
particularly in regions of fairly regular topology (such as, for example, the esophagus) where tissue-probe distances throughout the imaged area can be readily extrapolated from the value measured at the center of the field. In addition, topology of
the illuminated region may also be adduced by looking at the size and shape of the illuminated region. 
  
 [0039] A camera 68 is affixed to the proximal end of the endoscope 64. The images may be captured with a high-speed black-and-white charged coupled device (CCD) camera (SensiCam VGA, Cooke Corporation, Auburn
Hills, MI) and sent to a PC computer 70 that performs the function of the analyzer in FIG. 2. PC 70 may contain software and/or hardware for image analysis, classification and display. Camera 68 may be an independent unit proximately mounted to
apparatus 64, or an integrated part of apparatus 64, such as an embedded camera chip. Camera 68 is preferably capable of high-speed operation and broad sensitive spectral response for image acquisition. 
  
 [0040] FIGS. 6A and 6B show examples of other configurations of collection components
36 which may be used. As shown in FIG. 6A and 6B either polarizing sheets 76 or polarization beam splitting optics 84 can be used to split the parallel and perpendicular polarizations. Collector 36 can include imaging optics 40. Collector 36 may
include a portion of optical fibers 79 and 80 or a lens assembly which provide a second optic path 78. The collector 36 may also include collection optics as shown in FIG. 6B. Collector 36 may include a tunable filter 24 such as an AOTF-tunable
imaging filter (ChromoDynamics, Inc.). 
  
 [0041] The fiber optic path
provided by the collector 36 may provide a coherent imaging bundle or bundles of optical fibers to deliver images to external camera 68, or to focus the images onto a camera chip (not shown) within endoscope 64. This may also be done by an
appropriately designed lens assembly instead of optical fibers. If collection components 36 includes a tunable filter 24 (not shown), tunable filter 24 may be located at any suitable location in the light path. 
  
 [0042] FIGs. 6A and 6B are intended to illustrate that numerous alternative
embodiments of the present invention may be devised by those of ordinary skill in the art. The exact sequence of tuning, polarizing and focusing the light, and whether the tuning is performed on the input side (i.e. prior to the target) or the
output side (i.e. after the target) is of no consequence to the present invention. Many components other than those disclosed may be used to perform the desired function, and the selection of one type of component over another may dictate other
components that need to be in the light path. Thus, while the present invention has been described in conjunction with presently preferred embodiments, those of ordinary skill in the art will recognize that many modifications and variations are
possible. The present invention is intended to be limited only by the scope of the following claims and not by the scope of the disclosed exemplary embodiments.
