摘　　要：为了实现二进制加法符号替换规律,本文提出了一种简单的光逻辑系统,它仅包括一片二维列阵光学双稳器件.本实验采用同时具有NXOR和OR逻辑功能的透反射型ZnS光学双稳干涉滤光片作光逻辑器件.该光学逻辑系统完成了二进制加法四个符号替换规律的并行替换.光学系统采用固定的自由空间互连方法,具有光学硬件少,光功率损耗低,结构简单、实用的优点.For realizing symbolic substitution rules of binary addition. This paper proposes a simple optical logic system which includes only one 2-D array of optical bistable device. One optical bistable ZnS IF of transmission-reflection type which simultane-ausly has two logic functions of NXOR and OR as optical logic device is used in this arithmetic system. The invariable free space interconnect is adopted in the optical system. Four symtolic substitution rules of binary addition can be parallelly implement in the optical logic system. The optical logic system has the advantages of fewer optical hardwares, lower loss of optioal power and simple architecture.
