Description
Summary:Many image processing applications require a small, low-power, low-cost pattern recognition system that is capable of locating and identifying objects. Miniature optical correlators can perform 2-D pattern recognition at greater rates than digital platforms of equivalent size, power and/or weight. The patented miniature ruggedized optical correlator (MROC™) module is built to meet the environmental, size, power, and weight requirements of military and rugged commercial applications, and at a cost that permits wide deployment of the capability. The second version of the MROC module consists of a ferroelectric liquid crystal (FLC) device in the input plane for high light efficiency and incorporates a reflective magnet-optic spatial light modulator (RMOSLM™) device in the filter plane for very high speed operation. The correlator has a volume of approximately 20 MROC II breadboard tests demonstrated excellent correlation peaks, i.e., excellent discrimination at pattern matching rates of 1920/s on images of military vehicles. ©
