Abstract

An optical symbolic substitution using lenslet arrays is presented. By using the shift and the superposition properties of the lenslet array, the recognition and the substitution phases can be performed. The advantages of using the lenslet array for symbolic substitution are efficiency, cascadability, and high resolvability. Experimental demonstrations of the proposed symbolic processor are provided.
