Time-integrating acousto-optical processors

摘要

Disclosed are acousto-optical information processors employing a two- dimensional, time-integrating architecture. These three-product type processors are multi-purpose processors which can perform a variety of complex signal processing operations in two-dimensions, without requiring two-dimensional spatial light modulators. Typical of these processing operations are two-dimensional correlation, spectrum analysis, and cross ambiquity function processing. Some of the two-dimensional processing operations are made possible by the incorporation into a two- dimensional correlator of a distributed local oscillator, which may be implemented with mechanical-optical or electro-optical techniques. The acousto- optical processors may be easily implemented with readily available optical and acousto-optical components.
