本文讨论了作者所提出的白光信息处理系统的基本概念,以及用它在进行复数滤波、信号综合及平行光学处理诸方面的若干研究成果。这种方法既消除了相干系统中不可避免的相干噪声,又保持了相干系统所具有的运算能力。值得指出的是,它还具有相干系统所不具有的独特优点,即由于光源本身的相当广阔范围的光谱分布,对多色信号及彩色图象的处理十分有利和相当有效。它为光学信息处理展示了一个新的具有良好前景的方向。

We will describe a technique of white light optical information processing with diffraction grating method and some of their applications. This white light technique enables the signal processing to be carried out in complex amplitude rather than in intensity. The basic advantage of this white light processing technique is the elimination of the coherent artifact noise that frequently plagues the coherent optical system. We note that this white light processing technique is capable of processing many complex signals that a coherent prooessor may offer. The applioation may range from complex signals that a coherent prooessor may offer. The application may range from complex signal addition, subtraction, to complicated optical parallel processing. Because of the use of spectral broadband light source, this technique is very suitabla for color-image processing, enhancement, and restoration. Experimental demonstrations of this white-light processing technique as applied to archival storage of color films, multi-image rageneration, spatial frequermy and density pseudocolor encoding, smeared image restoration, etc. will be included.
