Optical Parallel Array Logic System

Abstract

The Optical Parallel Array Logic System (OPALS) is a parallel optical digital computing system using optical array logic as its operational basis. Its salient features are the capability of implementing fully 2-D parallel logical operation, parallel neighborhood operation, iterative processing, and programmability. In this paper, we represent optical array logic and realizable versions of OPALS's. 1-4 Then we briefly describe programming in optical array logic and the concept of pattern logic useful for space-variant processing with optical array logic.
