Abstract

Quantex's electron trapping (ET) materials are investigated as an integrated spatial light modulator (SLM) at the filter plane in a joint transform correlator (JTC). The ET based spatial light modulator can detect visible incoherent light, store an image pattern, and modulate the incoming coherent infrared light. Such a JTC architecture eliminates the electronic-to-optical and optical-to-electronic conversion between the square law detector and the next SLM in a joint transform correlator.
