Abstract Optical implementation of pattern fuzzy logic based on shadow casting is reported. In particular, a new spatial encoding method for fuzzy logic variables is proposed to optically realize the maximization and minimization operations needed by fuzzy logic. Experimental results are also given. © 1992 John Wiley & Sons, Inc.
