Abstract

Optical implementation of logical operation is an important subject in digital optical computing. For example, optical array logic (OAL),¹ symbolic substitution (SS),² binary image algebra (BIA),³ and image logic algebra (ILA) ⁴ are typical methods for implementing optical parallel logic. Recently, optical implementation of fuzzy logic based on area-coding technique (ACT) has been proposed. ³ These methods treat image data as an information medium for parallel processing. Image has inherent features which are not only parallelism for processing but also visual interface for human. In short, the availability of visual techniques leads to the development of new approaches that are inherently visual.
