Abstract:

Theoretical and experimental studies of two distinct electro-optic systems for automatic pattern recognition are reported. One uses a novel wide-band frequency plane filter, i.e., an achromatized holographic matched filter system. The second uses a virtual twin-image interferometer together with a Fourier achromat and a photodetector to form a hybrid electro optic processor that is potentially capable of high rate automatic sorting for incoherent imagery of very large space-bandwidth product. Both have been studied using noncoherent spectrally broadband illumination. Also excellent progress is reported on our related studies of broadband holographic optical elements and an off-axis Fourier transform achromat. With coherent illumination the author reports a means for automatic image quality evaluation. The scattering of light by dielectric and conducting cylinders has been studied theoretically and experimentally with an emphasis on remote optical metrology. Author
