Portable 512 x 512 Grayscale Optical Correlator

摘要

JPL is developing a portable 512 x 512 Grayscale Optical Correlator (GOC) system for target data mining and identification applications. This GOC system will utilized a pair of 512 x 512 Ferroelectric Liquid Crystal Spatial Light Modulator (FLCSLM) to achieve 1000 frames/sec data throughput. Primary system design issues including: optics design to achieve compact system volume with fine tuning capability, photodetector array with onboard postprocessing for peak detection and target identification. These issues and corresponding solutions will be discussed.
