Abstract

Coherent optical systems have the capability for performing two-dimensional data processing operations at high speeds. Applications of these systems have been made to pattern recognition, character recognition, spectral analysis, and the processing of a wide variety of optical and electrical signals. The full potential of optical processing has, however, not yet been realized. To increase the flexibility and, therefore, the applicability of optical process we need (1) an input interface device which converts electrical signals or incoherent optical signals into coherent optical signals, (2) an in situ recording material, which is reversable, for constructing spatial filters in real-time, and (3) an interface device which converts the optical output of the processor into an elec-trical signal.
