ABSTRACT:
An optical correlator system having a plurality of both active and passive reflective optical components between a source of electromagnetic radiation, such a visible coherent light, and an output detector array in a planar support body along a folded optical axis beam path within the body uses a ferro-electric liquid crystal spatial light modulator as the input sensor and the correlating filter to provide enhanced optical detection of an unknown object at a CCD detector array.
