Since symbolic substitution was first introduced by A. Huang in 1983, architectural concepts of processors using optical interconnects at the innermost level have become clear. We use the concept of an optical cellular automaton to present a simple, yet general description of one class of architecture, namely that of fine grain, massively parallel, space invariant binary processor arrays. The concepts are best developed in terms of pattern recognition, relevant optical systems approaches to the pattern recognitions desired include the sum of product and the cascaded product schemes. Several examples are given to illustrate the general ideas.
