ABSTRACT:
A discoid optical correlator system having a plurality of reflective optical components, a source of electromagnetic radiation, such as visible light, and an output detector which are positioned around the rim region of a solid disk body to develop a symmetrically folded optical axis traversed by a beam of electromagnetic radiation so that an unknown object is optically detected and identified.
