Abstract

Signal processing is an interesting field for all-optical digital computing. One reason for this is the fact that signal processing operations can be pipelined very efficiently. This eliminates the need for a complex memory system as it is required for general purpose systems. For example, we consider the M-transformation. The M-transformation is a binary signal transformation which requires only the implementation of AND and OR operations. It belongs to a class of shift-invariant transformations which are described in Ref. ¹. The property of shift-invariance makes it interesting for pattern recognition applications. We propose an optical implementation for 2-D signals, which is based on the use of crossover interconnections.
