Abstract

A technique for the experimental implementation of fully complex filters with commercially available spatial light modulators (SLMs) is reported. The filters are incorporated into an all-optical correlator and a hybrid digital-optical correlator, the relative merits of each configuration being considered. Various filter functions requiring complex modulation are demonstrated, consideration being given to the degradation of filter performance due to the limited quantization and dynamic range with which they can be implemented using current SLM technology.
