ABSTRACT:
A polychromatic optical correlator system, comprising one or more devices to generate simultaneously a plurality of signal beams at a plurality of wavelengths, a beam recombiner to direct the signal beams along an axis to form a multicomponent, multiwavelength beam comprised of those signal beams, at least one view exposed to the signal beams to spatially modulate each of the signal beams, and a matched filter plate having a plurality of matched filters stored therein. A multiple beam generating holographic lens is located in the path of the multicomponent, multiwavelength beam to deflect each of the component signal beams thereof onto the matched filter plate, with each of the signal beams being focused on a respective one of the matched filters of the matched filter plate. Optical detection is located in the paths of output beams of the matched filter plate, to produce a signal when the correlation between the pattern of one of the signal beams focused on the matched filter plate and the matched filter on which that one beam is focused, rises above a predetermined value.
