Abstract : The report describes the progress in optical coherence theory and optical information processing during the year 1968. The optimization problem for optical systems consists of two parts, (1) the maximization of optical transcoherence between the input and output of an optical lens system and transducer, and (2) the minimization of statistical errors by the appropriate application of decision theoretic concepts to processing. The statistical techniques suggested are based upon information theory, optical coherence theory, and space-time decision theory. Both a field and an intensity transcoherence theory have been de developed, where the latter is applicable to systems which record intensity only (e.g., film). One of the major problems has been that of developing an appropriate computer algorithm for optimization of the system by means of maximization of transcoherence functions. An interesting new technique, suggested by Rosenbloom consists of formulating the fields in terms of a quasi-geometrical optics approach first used by Luneberg. A number of possible applications are considered, including aerial photography, optical radar, and optical communications systems. (Author)
