Image Synthesis System for Optical Pattern Recognition/Optical Correlation

To avoid li#iitations imposed by conventional spatial light modulators in two-dimensional optical pattern recognition/correlation systems, a hybrid optical-electronic system combining the throughput benefits of optical processing and accuracy of digital processing is proposed. This optical processing system is based on the Essex patented ImSyn(TM) processor which combines optical and digital integration to achieve high dynamic rnage. Tile proposed processor is based on a processing method that uses both phase and amplitude information to produce true complex transforms. Because the processor operates on complex data, improvements in pattern recognition performance may be achieved over traditional optical methods which use either amplitude-only or phase-only processing. The complete hybrid system can be manufactured in a small, low power, and lightweight package for use in automatic targeting of small munitions. The Phase I effort will be directed toward concept demonstration on a laboratory prototype system, development of a detailed design, and the preparation of a Phase II work plan. The Phase II effort will be to build and deliver an optical pattern recognition/optical correlation processor suitable for flight demonstration.
