    Holographic Applications in Medical Imaging and Photovoltaic Energy Systems


    Volume holographic optical elements have a number of features that can provide new functionality to optical systems. In this presentation a review of some of these features will be presented. Following the introduction two different systems with very different requirements will be considered and it will be shown how volume holography can be used to advantage. The first system is a volume holographic imaging system (VHIS) that acts similar to a confocal microscope. The difference is that scanning is not required for VHIS and greatly simplifies the design. A benchtop and endoscope version of the VHIS has been implemented are currently being used in clinical trials. The second application is in solar energy conversion. Solar concentrators, light trapping elements, and spectrum splitting filters have been realized and will be discussed. Finally the capability of these systems is realized through the use of holographic recording materials with very different properties.  A review of the polymer and dichromated gelatin materials used for these applications will also be discussed.

    Professor Raymond K. Kostuk has a joint professor position with UA’s ECE Department and the College of Optical Sciences. He received a B.S. in Physics and Math from the U.S. Coast Guard Academy (1972) and served for 10 years as an officer in the U.S. Coast Guard. While serving he obtained a M.S in Optical Engineering from the University of Rochester (1977). He received a Ph.D. in electrical engineering from Stanford University (1986) working under Professor Joseph W. Goodman. After completing his PhD. he spent a year at the IBM Research Center working on optical storage problems and became a professor at the U of A in 1987. His primary area of expertise is in holographic concepts, materials, and applications. He is a Fellow of the Optical Society of America and the Society of Photo Instrumentation Engineers (SPIE).
