Abstract
An amplitude encoded lens function signal, similar to a zone plate, is formed in the transform plane of a chirp encoded joint transform correlator. CCD correlation spot light sensor is separated from the transform plane by the focal length of the encoded lens function, and generates the desired output correlation spot. As a result, no prior art inverse transform lens need be provided, which simplifies the design. Further simplification is attainable in a low noise commercial image matching environment by eliminating the CCD correlation spot sensor entirely, and verifying an input image/reference image close match by using the eye of an operator to check for the presence of the visible zone plate, indicative of such a match.
