Abstract : There have been a number of significant advances in digital optical computing research over recent years. Experimental demonstrations of optical restoring logic, the lock-and clock control of data flow, a programmable optical logic unit, optical switching networks, and parallel logic modules have shown that the basic building blocks for a parallel digital optical computing system now exist. This paper describes recent work carried out at Heriot-Watt University in which such a demonstration optical processor has been constructed. The architecture chosen for the demonstrator project corresponds to the Cellular Logic Image Processor (CLIP). In this implementation, the CLIP may be regarded as an optical co-processor residing within a host electronic computer which provides all the necessary control and clock signals.
