ABSTRACT:
An optical correlator memory processing system. By operating the system within preselected maximum and minium wavelengths, by preselecting certain parameters of the system, and by operating the system within certain additional constraints, the system can be used to always cause interference between the Fourier transform of a spatially modulated signal beam and a reference beam at a recording medium at a multitude of wavelengths. This allows a matched filter to be fabricated and played back at these multitudes of wavelengths without changing the sensitivity of the system. The system may be used to fabricate matched filters, and as a correlation system to detect the presence or absence of a particular target in a selected view or scene.
