世界上一百多个领先实验室的数十名研究人员正在努力为新的工程领域奠定基础，该领域有望对几乎每个科学技术领域产生革命性的影响。由于引入了各种新技术和设备（包括激光）以及新的光敏和电子束记录材料（包括热塑性塑料、可编码薄膜和大容量存储全息存储器）的开发，这种称为光学计算的新技术基于称为相干或傅立叶光学和全息术的数学概念。就未来的发展和应用而言，最引人注目的结果很可能来自各种形式的实时图像处理的实施。但光学计算的强大能力主要源自其新近公认的并行处理能力，这是镜头的自然属性！一般来说，这个新领域的所有方面都可以用电气和电子信号处理和通信的既定概念来表征。
Dozens of research workers in more than a hundred leading laboratories of the world are working on creating the foundations for a new field of engineering that promises to have a revolutionary impact on almost every field of science and technology. Resulting from the introduction of a variety of new techniques and devices-including the laser-as well as from the development of new photo-sensitive and electron-beam recording materials-including thermoplastics, codable films, and mass-storage holographic memories-this new technology, known as optical computing, is based upon mathematical concepts known as coherent or Fourier optics and holography. In terms of future developments and applications, the most dramatic results very likely will emerge from the implementation of real-time image processing in various forms. But the great power of optical computing derives primarily from its newly recognized capability of parallel processing, a natural property of the lens! In a general way, all aspects of this new field can be characterized by established concepts of electric and electronic signal processing and communications.
