Abstract

A flexible processing scheme for various types of structured data is presented. The scheme is based on optical array logic, which is a technique for parallel neighborhood operation using spatial coding and 2-D correlation. In the proposed scheme, virtual processing elements are constructed on an image plane and their functions are emulated with optical array logic. Such a processing system can easily be controlled by programming in optical array logic, so that flexible-structured data processing can be achieved. Several computer simulation results are presented. Referring to the results, requirements for optical implementation are discussed.
