Paper Abstract

The use of acousto-optic processors in applications such as radar signal processing and spectrum analysis places high performance requirements on the optical detectors used to detect the processed signal. In many signal processing applications there is a need for high speed, high dynamic range detectors with commensurate crosstalk and image lag performance. A program supported by Harry Diamond Laboratories for improved performance of CCD detectors has been highly successful in reducing crosstalk and obtaining over 40 db of optical detection dynamic range in the zero image lag mode of operation. Two different types of epi- layer structures, P on P+ and P on N, have been fabricated for which the methods and design issues to achieve high dynamic range, low crosstalk, low image lag, and high speed are discussed. The design approach used to suppress blooming is also discussed and the results of recent devices testing are shown.
