Paper Abstract

An optical correlator using incoherent light was exploited with a composite filter comprised of a multiplicity of sub-filters to simultaneously detect the presence of a number of objects or alternatively allow rotation and scale changes of one object. We determined that for high SNR it is necessary to record the sub-filters with diffused light. Moreover for a certain geometry of the correlator the sub-ifiters diameter can be as low as 4 mm without significantly affecting the correlation performance. 1.
