Abstract

A hybrid digital/optical joint transform correlator that requires only one spatial light modulator has been designed, constructed, and demonstrated. This was accomplished using a novel video rate multiplexing and demultiplexing circuit that alternates frames of video addressing the SLM. Demonstrations using a modified liquid crystal television and a Faraday effect magneto-optic device show that the performance of the single SLM arrangement is essentially the same as that from the traditional two SLM architecture. The circuit utilizes common electronic components and requires a very small amount of power.
