Abstract : Experimental work with a compact, coherent, real-time optical correlator and a matched filter maker system is described. The system was designed and built by the technical staff of The Environmental Research Institute of Michigan. Attributes of the correlator included small size, the ability to correlate an input image with multiple references, and operation over a wide range of input light levels. The input scene enters the correlator by a system of lenses while the matched filters are prerecorded on a photographic plate that is inserted into the correlator. The correlator contains a miniature CCD television camera upon which the correlations are projected. The output of the camera is a standard composite video signal which can be displayed on a simple monitor. A match between the input scene and one of the stored filters is indicated by the appearance of a bright correlation spot on the output monitor. (Author).
