UNDERSTANDING IMAGE FORMATION

      June 15-16, 1992
         Hyatt Hotel
     Rochester, New York
=============================

Course Objective
----------------
This course is intended for workers in a variety of fields involving
image formation.  Its basic thrust is practical, with an emphasis on
physical explanations and heuristic understanding.  Theory is provided
for rigor, as required, but class time will not be spent on mathematical
derivations.  The principal content of the course is a general treatment
of partially coherent imaging, which is ubiquitous, but not widely
understood, largely because it has obtained an unjustified mystique of
difficulty.  The subject can, in fact, be made quite digestible when
based on the phenomenological treatment of partial coherence used by H.
H. Hopkins, which sidesteps the complexities of statistical optics. 
Moreover, such a treatment of image formation can be remarkably broad. 
Coherent and incoherent image formation are included as special cases,
and a wide range of imaging configurations can be treated within the
same framework.  In addition, many scanning systems have projector
equivalents, so the same analysis and simulation programs can be used
for these.  The fundamentals provided by this course, coupled with a
general purpose image simulation program, will provide a basis for the
development of expertise in any particular area of image formation.  The
wide variety of systems to which the material applies include the
following:

    * Projectors and microscopes
    * Pupils with obstructions and apodization
    * Zernike phase contrast
    * Differential interference contrast (Nomarski)
    * Schlieren systems
    * Knife-edge testing
    * Brightfield and darkfield illumination
    * Ring, line, and point sources
    * Scanning microscopes, including confocal
    * Optical storage reading heads
    * Photolithographic tools

Prerequisite
------------
A basic understanding of interference, diffraction, and imaging is
needed, on the level of an optics survey text, such as "Optics," by
Hecht.

Instructor
----------
Douglas Goodman received his Ph.D. in Optics from the University of
Arizona in 1979, where his thesis work was on image formation.  Since
then, he has been a Research Staff Member at the IBM TJ Watson Research
Center, Yorktown Heights, NY, working on a variety of areas of applied
optics, including photolithography, alignment, illumination, optical
inspection, microscopy, and metrology.  He is a Fellow of the Optical
Society of America, with an interest in education and in the
organization of knowledge for more efficient learning.  He has written a
book chapter "Survey of Optical Instruments" in "Geometrical and
Instrumental Optics", D. Malacara ed (1988), and has taught a number of
short courses at OSA and SPIE meetings within IBM.
