Implementation, Control and Programming of Digital Optical Systems
Available from UMI in association with The British Library. Optical technology is playing an increasingly important role in modern computer systems including such areas as communications via fiber optic systems and data storage in the form of the optical compact disk (CD-ROM's). One of the aims of research into this technology has been to extend and enhance existing electronic computing systems. This thesis represents work carried out on the implementation of one particular form of parallel digital optical computing architecture known as the optical cellular logic image processor. This architecture performs the information processing all-optically and in parallel while making use of electronic technology for timing and control. One particular component required in this architecture is some form of programmable processing unit. Experimental studies involving the construction of single channel optical processing units were successfully completed. These units had multi-function capability and could be programmed optically under electronic control. Expansion upon one of these basic units to include iterative feedback resulted in the successful implementation of a single channel of the cellular logic image processor architecture. It allowed eight functions to be programmed in real time and demonstrated some of the world's first all-optical digital processing of arbitrary optical data. Further expansion of the system to include 256 simultaneous processing channels using similar technology was also partially completed. A full description is presented of the design concepts, components and the systems that have been developed. Attention is also given to both the hardware and software aspects related to electronic control of the optical systems. Finally, limitations associated with present optical technology are discussed and future possibilities suggested.
