A white light optical processor is described using partial coherence theory. The application of the processor to both edge enhancement and band-pass filtering of imagery is discussed. The spectral components of the spatial frequency content of images can be separated or filtered if the various spectra do not overlap by a distance determined from the spatial spectrum of the mutual intensity function of the image illumination. The results of an experimental and computer evaluation of the processor are presented.
描述了一种基于部分相干理论的白光光学处理器。讨论了该处理器在图像边缘增强和带通滤波方面的应用。如果各种光谱之间不重叠的距离由图像照明互强度函数的空间光谱确定，那么图像空间频率内容的光谱成分就可以被分离或滤波。给出了该处理器的实验和计算机评估结果。
