一种新型的白光信息处理系统

A NEW OPTICAL INFORMATION PROCESSING SYSTEM OF THE WHITE-LIGHT SOURCE

最近,我们研究出一种自光信息处理系统,并应用于遥感图像(包括卫片、航片及侧视雷达图片)的处理,取得了较好的效果.与同类型的光学处理方法相比,具有操作方法简便,对设备、环境要求低,处理速度快等优点.

A new system in white-light optical information processing is described. This system adopted two point sources,one black and white photographic image and once-through encoding,by color filtering of the smeared Fourier spectrums two or three colors pseudocoloring can be obtained,it can be call- ed“TOOT”system,means“Two One Once Two(or Three)”system.This system can be used for density pseudocolor encoding or spatial frequency pseudocolor encoding and it is capable of performing most optical test in the coherent optical processing.This system is inexpensive and simple to operate,it also provides the advantage of direct-viewing capability with arbitrary sizes.It is more convient for practical purpose,and since the pseudocolor encoding is obtained from a white-light source coherent artifact noise is eliminated.
