Coherent Optical Correlator.
Abstract
The real time coherent optical processor will operate using realistic, low resolution input imagery. The system incorporates a bank of reference images to provide the capacity for handling variations in aspect, rotation, and scale. This bank is scanned in time so that it can be determined which reference images are providing correlation signals. The input device is an optically addressed image forming light modulator which can be operated by imaging on it an object or scene illuminated with bright artificial light or sunlight or by imaging a television monitor on cathode ray tube image of an object or scene. An array of laser diode light sources is used to interrogate an array of stored reference image transforms by selectively turning on diodes in the array. (Author)
