Nonlinear Real-Time Optical Signal Processing.
Abstract
During the period 1 July 1985 - 30 June 1986, the research under Grant AFOSR-84-0181 has concentrated on various aspects of optical digital computing. We have continued detailed studies of a sequential optical parallel computing architecture whose wiring is implemented by computer-generated holograms. We have studied the implementation of various specialized processors such as cellular logic processors on this architecture and have examined high space-bandwidth interconnection holograms that serve this purpose. The implementation of some architectures such as cellular hypercubes and pyramids are not feasible for electronic VLSI, but are more easily suited to the page-oriented architecture of a 2-D digital optical array. We have also examined mathematical morphology as a basic image algebra for cellular logic image processing, and found that three fundamental image operations: complement; union (or intersection); dilation (or erosion) are sufficient to implement any binary morphological function. A final area of study has been the investigation of abstract parallel computing models in the context of the physical constraints and technology of optical computing. These models include shared memory and graph/network models. (Author)
