Abstract

This paper describes an optical correlator system that uses binary-phase-only filters (BPOFs) for target identification, tracking and discrimination. The optical system is a modification of previous correlator designs. The system incorporates a telephoto lens pair and simplifies the output optics such that the total optical-processor system length is reduced to fractions of a focal length. A Vernier scale adjustment of the optical Fourier transform is also made possible. Extensive software was developed to generate and manipulate target and filter files including the generation of BPOFs and the sequencing of files to drive the spatial light modulators. Examples are shown of autocorrelation and crosscorrelation of the target and filters.
