光学信息处理可以执行无数的信号处理操作。这主要是由于复振幅处理能力。光学信息处理器能够使用简单的线性算子执行一维或二维运算。然而，如果没有照明的相干性的支持，这是不可能发生的。本文将讨论利用光学复变换进行信息数据处理的问题。重点介绍傅立叶和空域处理、复合滤波、三维模式识别、大容量光折变处理、光学神经计算等。
Optical information processing can perform a myriad of signal processing operations. It is primarily due to the complex amplitude processing capability. Optical information processors are capable of performing one- or two-dimensional operations using simple linear operators. However, it would not happen without the support of coherent property of illumination. In this paper we shall discuss the inherent optical complex transformation, by which information data processing can be exploited. Fourier and spatial domain processing, composite filtering, 3-D pattern recognition, larger capacity photo-refractive processing optical neural computing and others will be stressed.
