Abstract

Optical computing is a powerful information processing paradigm for massively data owing to attractive features of light such as parallelism, flexible connectivity, high density connectivity. Digital optical computing is most promising because of accuracy and processing flexibility. Several paradigm of digital optical computing have been proposed. [1-4]. These paradigms can provide space-invariant logical operations for digital and discrete image in parallel. In processing sequences of the paradigms, digital discrete correlation is considered as an essential operation. Efficiency of optical parallel digital discrete correlator (OPDDC) determines that of optical digital computing system. Although a lot of implementation have been presented, there are few systematic study on this subject.
