    Holographic Applications in Medical Imaging and Photovoltaic Energy Systems

    Abstract(s): 

    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.

    Speaker Bio(s): 

    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. degree at the U.S. Coast Guard Academy (1972), an M.S. from the Institute of Optics at the University of Rochester (1977), and a Ph.D. in electrical engineering from Stanford University (1986). After completing his Ph.D. he spent a year at the IBM Research Center in Almaden, California. His primary area of expertise is in holographic concepts, materials, and applications. He is currently investigating the application of holography and low coherence techniques to medical imaging problems. He has projects on optical coherence tomography and the use of volume holograms for obtaining spatial and spectral information from biological tissue. In another effort he is investigating the use of holographic optical elements to realize compact non-conventional solar photovoltaic concentrators. His group is also investigating holographic techniques to enhance the optical collection efficiency of low cost photovoltaic cells with laminate nanostructures and to develop holographic spectrum splitting concentrators. He is a Fellow of the Optical Society of America and the Society of Photo Instrumentation Engineers (SPIE) and served as the holography associate editor for Applied Optics. He has recently been the Kenneth Von Behren Professor of ECE, the co-chair of the holography working group for the SPIE, and a Member of the IEEE.
