Paper Abstract

Recent developments in noncoherent optical processing suggest that hybrid incoherent optical/electronic systems represent a viable alternative to coherent optical systems for diffraction-limited parallel processing of two-dimensional signals. Favorable characteristics of incoherent systems include greatly simplified input transducer requirements and a redundancy or multichannel nature that makes them resistent to the blemish noise typical of coherent processors. In this paper we discuss the basic kinds or classes of hybrid optical/electronic methods for bipolar processing of two-dimensional signals using two-pupil optical systems: direct subtraction and carrier, pupil interaction and non-pupil interaction. Tradeoffs and limitations are considered, and a new method for realizing a general bipolar pointspread function with positive-real pupil transparencies is presented.
