Description
BACKGROUND OF THE INVENTION The subject application is directed to a system with all-optical coupling of an optoelectronic probe and an optoelectronic measuring console. In particular, the subject application is directed to an optoelectronic probe system employing all-optical coupling, which allows for a cost effective, safe, and expedient operation of an optoelectronic probe used in optical measurements.
Optoelectronic measuring techniques, such as, for example, spectroscopy implementing reflectance, light-elastic scattering, or fluorescence, and optical imaging, such as confocal microscopy and optical coherence tomography, typically involve the use of an optoelectronic probe to allow for delivering optical radiation to an associated sample.
Conventionally, the architecture of these devices includes an optoelectronic measuring console and a permanently attached or detachable optoelectronic probe, having optical and electrical communication with the optoelectronic measuring console. The optical communication is typically employed using one or more optical fibers, wherein the electrical communication is provided via electrical wires, as known in the art. Such architecture is definitely simple and cost effective, but has several drawbacks.
By way of example, a galvanic electrical contact between an optoelectronic measuring console and an optoelectronic probe, wherein the optoelectronic measuring console typically has hazardous voltages inside, represents a risk of electrical hazard to an operator and/or patient, since the optoelectronic probe is in contact with an operator and, in the case of biomedical use of the device, with the patient tissue. This risk is typically mitigated by appropriate design of the device, at the expense of additional design, manufacture, validation, and regulatory efforts. In particular, probe circuitry can be galvanically insulated from the rest of the optoelectronic measuring console, using optoelectronic type, capacitor-type, or inductive-type means. However, these means bring additional cost and complexity to the device, especially when medical-grade insulation is required.
Combined electro-optical connectors, i.e. having both optical and electrical contacts, are substantially more expensive and frequently inferior in performance in comparison to optical only or electrical only connectors. The use of separate optical and electrical connectors with a subsequent junction device is also known in the art, but the junction device represents additional cost and complexity as well, especially when medical reprocessing is required, such as disinfection or sterilization.

Next, the mixing means 314 receive from the optoelectronic probe 306 an optical signal supplied by the transforming means 318 via the optical connector means 304. The mixing means 314 then selects from the received optical signal, an optical signal representative of the optical signal returning from an associated sample, and selects an optical signal representative of an auxiliary optical signal returning from the second auxiliary means 326. The mixing means 314 then directs the optical signal representative of the optical signal returning from an associated sample, to the regular optical part 308 of the optoelectronic measuring console 302. The optical signal representative of the optical signal returning from the second auxiliary means 326 is directed by the mixing means 314 to the first auxiliary means 312 via the directional means 316.
As will be recognized by those skilled in the art, the second auxiliary means 326 is capable of providing a unique identification of the optoelectronic probe 306, storing calibration parameters of the optoelectronic probe 306, counting events, such as number of sessions used, time in use, and the like, and communicating this information to the optoelectronic measuring console 302, as described in detail above.
Referring now to operation of the optoelectronic probe system with all-optical coupling 400 in accordance with the subject application shown in FIG. 4, the operation of the optoelectronic probe system 400 commences analogous to that described with respect to the embodiments of FIGS. 1 through 3. A supplemental optical signal is then generated by the supplemental optical signal source 414 comprised in the optoelectronic measuring console 402. The supplemental optical signal and the output signal from the regular part 412 of the optoelectronic measuring console 402 are communicated to the optoelectronic probe 406 via the corresponding channels 408, 410, respectively, of the two-channel optical connector means 404. The optoelectronic probe 406 receives the first optical signal, representative of a supplemental optical signal from the supplemental optical signal source 414, and receives the second optical signal from the optoelectronic measuring console 402 via corresponding channels 408, 410 of the two-channel optical connector means 404. The converting means 418 then converts the first optical signal into an electrical signal, which is delivered to the electrically controlled module 416 via the first delivering means 424, analogous to that described above with respect to the embodiment of FIG. 1. The second delivering means 426 delivers the second optical signal received by the optoelectronic probe 406 to an associated sample 428 for operating the optoelectronic probe 406. As will be recognized by those skilled in the art, further operation of the optoelectronic probe system 400 is analogous to that described with respect to the embodiment of FIG. 1.
Referring now to operation of the optoelectronic probe system with all-optical coupling 500 in accordance with the subject application shown in FIG. 5, the operation of the optoelectronic probe system 500 commences analogous to that described with respect to the embodiments of FIGS. 1 through 4. A supplemental optical signal is then generated by the supplemental optical signal source 514 comprised in the optoelectronic measuring console 502, and an auxiliary optical signal is generated by the first auxiliary means 516. The supplemental optical signal and the auxiliary optical signal are then directed by the directional means 518 as a first optical signal to the optoelectronic probe 506 via the corresponding channel 508 of the optical connector means 504. The optical signal from the regular part 512 of the optoelectronic measuring console 502, which is a second optical signal, is communicated to the optoelectronic probe 506 via the corresponding channel 510 of the optical connector means 504. The second delivering means 532 then delivers the second optical signal from the optical connector means 504 to an associated sample (not shown) for operating the optoelectronic probe 506, and thereinafter delivers an optical signal returning from an associated sample to the regular part 512 of the optoelectronic measuring console 502 via the corresponding channel 510.
As will be appreciated by a skilled artisan, the first optical signal received by the optoelectronic probe 506 via the channel 508 is representative of the supplemental optical signal from the source 514, and representative of the optical signal output by the first auxiliary means 516. The splitting and directing means 524 then splits the first optical signal into a first part and second part, directs the first part of the first optical signal to the converting means 520, and directs the second part of the first optical signal to the second auxiliary means 522. The first delivering means 530 then delivers the electrical signal from the converting means 520 to the electrically controlled module 528 comprised in the second auxiliary means 522, and to the electrically controlled module comprised in the distal part of the optoelectronic probe, such as described with respect to the embodiment of FIG. 4. The splitting and directing means 524 then directs an optical signal returning from the second auxiliary means 522 to the corresponding channel 510 of optical connector means 504. The optical signal returning from the second auxiliary means 522 is thereinafter directed by the directional means 518 to the first auxiliary means 516.
Those skilled in the art will appreciate that the second auxiliary means 522, analogous to that described above with respect to the embodiment of FIG. 3, is capable of providing a unique identification of the optoelectronic probe 506, storing calibration parameters of the optoelectronic probe 506, counting events, such as number of sessions used, time in use, and the like, and communicating this information to the optoelectronic measuring console 502. As will be further recognized by a skilled artisan, the embodiments of the optoelectronic probe system illustrated in FIGS. 3 through 5, when including power level altering means and indicating means (not shown in the drawings) operate analogous to that described above with reference to the embodiment of FIG. 2.
