Abstract

Logic gate processing with a new configuration of coding cells using one-dimensional spatial encoding cells is proposed. Applications of the proposed method, i.e., an optical array processor that can perform parallel operation of addition and subtraction for two binary variables without considering the carry mechanism, and gray-level image processing are presented. Experimental verifications are also performed.
