摘　　要：论述了一种实现百位量级三值光学计算机(TOC)实验系统中光学运算器及光学解码器同步的技术。该技术的原理是以光电传感器感应到的光强度变化来判断光学运算器的一次运算是否完成,若完成则通知光学解码器进行解码。受正在使用的三值光学计算机实验系统已有结构的限制,该技术采用了以光学解码器的控制器为核心、软件控制为主的方案。该方案虽然比纯硬件方案慢,但适合于目前的低速度实验平台,而且便于改进,本身也成为研究三值光学计算机部件间同步技术的一个实验子系统。描述了对当前的三值光学计算机实验平台和软硬件部件所进行的相应改造,实验结果表明了该同步系统的有效性和可靠性。An implementation technology of synchronizing decoder is presented with optical operator in hundreds-bit ternary optical computer（TOC） experimental system.The technology principle is that try to determine when the optical processor finishes its computation based on the intensity changes of light inducted by photoelectric sensors.Because of the limitation of the structure of currently used ternary optical computer experimental system,the controller of the decoder is used as the core and software as the main controller in the scheme.Though the solution is slower than that with pure hardware,it is a good choice for the current platform and easy to improve.What’s more,it will be an experimental subsystem of the synchronization research in ternary optical computer components.Besides,the improvement of the platform and software and hardware of TOC experimental platform is discussed.Experimental results demonstrate the validity and reliability of the synchronous systems.
