Abstract

Optical analog data processing systems are described for handling both bipolar and complex data. Multi-cell spatial light modulators are employed in which a plurality of modulation areas are used in conjunction with space and time mutliplexed configurations to process bipolar and complex data elements. Multi-cell light detector arrays are used to convert modulated light into signals representing the processed data. The processing systems are capable of real time processing of synthetic aperture radar data.
