Coherent optical processing for multisensor image processing

Abstract:
Coherent optical processing of multi-sensor imagery (with geometrical and intensity distortions) for pattern recognition and registration are considered. Sensor-invariant high information content image features are considered as well as the degree to which an aerial image need be converted to its true radar image for frame registration and map matching applications. Digital, electronic and optical edge enhancement, as well as the use of special features of storage-mode real-time spatial light modulators and parameter control in optical matched spatial filter synthesis are considered as adjuncts whereby the required final result can be achieved. The initial results of coherent optical correlations on actual multi-sensor imagery are reported.
