Abstract

A novel optical digital computing system called Optical Parallel Array Logic System (OPALS) is presented, which can execute cellular logic¹ in parallel. The system is constructed on the basis of the concept of optical array logic. The pure optical version of the OPALS can be realized by using a dynamic optical coding technique and optical correlation by a multi-focus imaging system. Although the OPALS is still a conceptual system, it would be expected to be a prototype of optical digital computing systems in future.
