Abstract

Optics has been successfully utilized to perform analog matrix-vector multiplication. It can be shown that any general purpose digital logic can be expressed in terms of two-stage binary matrix- vector multiplication or single-stage multiplication followed by a logical NOR operation. A logical inversion can be performed by the LCLV or the spatial light rebroadcaster material by multiwavelength exposure. The OR operation is then performed by a cylindrical lens. The complete process is then performed optically. Experimental results, future prospects, and related problems are discussed.^1-3
