Filter implementation technique for multicriteria characterization of coding domains in the joint transform correlator

An improved method for implementing correlation filters in the joint transf orm, correlator architecture is proposed. We derived the method fi om compu ter-generated holography techniques. It allows us to use any correlation fi lters, especially ones that provide an optimal trade-off between noise robu stness, peak sharpness, and optical efficiency, with any spatial light modu lator (SLM). This method also allows for an objective comparison of the per formance of the coding domains of various SLM's. (C) 1999 Optical Society o f America. OCIS codes: 070.5010, 070.4550, 230.6120.
