在推进光学存贮器的主要步骤方面,已发展了一种只要输入某些图象片断即能恢复贮存图象的装置。据报导,休斯研究实验室科学家研究的这种相关存贮器对实现可以反映大脑工作情况的所谓神经网络并行计算目标很有好处。经过通用汽车公司和休斯电子学公司改进后,这种系统用全息存贮图象作为数据库,把相位共轭镜加在全息图的两侧,共轭镜起着共振腔作用,并和所存 In the main steps of advancing optical storage, a device has been developed which can restore stored images by simply inputting some image segments. It is reported that the relevant memory researched by Hughes research laboratory scientists is good for realizing the parallel computing goal of the so-called neural network that can reflect the working of the brain. After the improvements made by General Motors Corp. and Hughes Electronics Corp., the system uses a holographic memory image as a database to add phase conjugate mirrors to both sides of the hologram. The conjugate mirror functions as a resonant cavity and interacts with the stored
