Abstract

A simple target which contains a wide variety of spatial frequencies has been developed for use in testing optical correlators. This target is designed to be complicated enough to provide an adequate test of many correlator and filter architectures, but yet simple enough to be used by researchers without the need for special equipment. Computer simulations and experimental results are presented for using the target in testing some correlator filter designs.
