Paper Abstract

Optical digital processing offers an opportunity to go beyond the speed limit of electronic computing mainly because optics. unlike electronics, is inherently suitable for highly parallel architectures. In this presentation we shall not discuss methods of making faster switches; rather, we shall look at how to use incoherent light to allow more gates to work at the same time. In an earlier work' we demonstrated the use of a lenslet array based device to provide interconnections for a simple binary "circuit." Other workers discussed the use of shadow casting for other signal routing problems.2 3 It is also possible to use OTF synthesis to provide convolution-like digital inter-connections, appropriate for problems such as image processing. Particularly, holographic incoherent OTF synthesis appears appealing because of its inherent flexibility. Here, we shall consider some candidates for future research in digital information processing with incoherent light. Some of these are Non-binary ("multiple value") digital logic;Cellular architectures; Neural model associative memory.
