Paper Abstract

Current electro-optical (E0) sensors are largely based upon image plane (post detector) processing. However such systems do not achieve the discrimination possibe between the sought after signal and natural interfering features in the background because they only respond to the time averaged intensity and thus throw away key information about spectral profile polarization temporal and spatial coherence phase profile etc. The paper describes techniques whereby differences in these characteristics are exploited to good effect by processing in the optical (pre-detector) domain the processing being achieved by the application of selective transformations which respond uniquely to the sought after signal''s characteristics.
