Abstract

Optical design considerations and performance results are presented for two compact hybrid optical correlators and a novel, subcompact correlator model; all operate with two metal-oxide spatial light modulators (SLMs) at HeNe and diode laser wavelengths. The 4F optical path of the former two correlators approximates 25 in., while that of the subcompact unit requires less than 13 in. for a 4F-equivalent path. The results obtained demonstrate superior performance relative to available devices.
