Distributed Processing in Continuous Optical Media

光神经网络领域是通过采用各种“连接主义”模型提出的技术而发展起来的。光学实现最早是由Psaltis和Farhat于1985年提出的。让我们来吧。10，98(1985)，随后由Anderson于1986 OPT进行了直接光联想存储器演示。让我们来吧。11，59(1986)和Soffer，Dunning，Owechko和Marom Opt。让我们来吧。11,118(1986)以及Yariv和Kwong Opt。让我们来吧。11,186(1986)。自那时以来，该领域发展迅速，考虑了许多见解、问题和方法。最有趣的是Psaltis和他的同事演示的中英三字识别和翻译，Anderson和他的同事的光学新奇跟踪过滤器，Lischer和Lee最近在N.R.L.所做的工作需要解决的一些问题包括多图像全息存储、学习的实现以及表现出大效应的更快的非线性晶体。

The area of optical neural networks has evolved by adopting the techniques proposed by various "connectionist" models. The optical implementation was first demonstrated by Psaltis and Farhat in 1985 Opt. Lett. 10, 98 (1985) and was followed by a direct optical associative memory demonstration by Anderson in 1986 Opt. Lett. 11, 59 (1986) and by Soffer, Dunning, Owechko and Marom Opt. Lett. 11, 118 (1986) as well as Yariv and Kwong Opt. Lett. 11, 186 (1986). Since this time the field has evolved rapidly and many insights, problems, and approaches have been considered. Most interesting has been Chinese to English three character recognition and translation demonstrated by Psaltis and co-workers, an optical novelty tracking filter by Anderson and co-workers, and recent work by Lischer and Lee at N. R. L. Some of the problems to be addressed include multiple image holographic storage, implementation of learning, and faster nonlinear crystals exhibiting large effects.
