Abstract

A new optical–digital computing system called OPALS (optical parallel array logic system) is presented. OPALS can execute various parallel neighborhood operations such as cellular logic as well as parallel logical operations for 2-D sampled objects. The system has the ability to perform iterative operations. OPALS is systemized, centering on the optical logic method using image coding and optical correlation techniques. The concept of array logic plays an important role in designing the OPALS, and new optical techniques for constructing the OPALS are proposed. Using these techniques, a pure optical version of the OPALS can be made.
