Abstract

Optical pattern recognition is widely considered a key operation in any hypothesis of optical computer or communication network fabric, in which it is necessary to identify at very high speed streams of digital data. Several correlators [1,2] have been investigated and can be considered good mainly in recognition of very different 2-D images [3,4,5].
