The military has invested significant resources for automatically locating and identifying enemy threats and high value targets. Automatic Target Recognition (ATR) systems using the output of imaging sensors, such as video, and Forward Looking InfraRed (FLIR) are continually being developed. The achievement of adequate processing rates required to analyze the tremendous amounts of data from these sensors remains a critical task in bringing these systems to the field. The two Optical Processing Identification Demonstration (OPID I and OPID II) program efforts, in their use of an optical processor, address the needs for both advances in system algorithms and data throughput enhancement.
