摘要
介绍一种对具有宽度的线状物体实现边缘增强从而达到识别目的的方法。利用置于相干系统傅里叶平面的光折变晶体ＣＵ：ＫＮＳＢＮ在一定条件下产生位相复共轭效应，从面形成拉普拉斯算子，最后在象平面输出线状物体的边缘增强象。文中给出实验结果及扼要的理论分析。
This Paper prestents a method which enhances the edge of linear objects with a certain width. The enhancement processing has been finished by using a photorefractive crystal Cu:KNSBN placed on the Fourier transform plane of the coherent system. Under certain conditions a Laplacian operator is formed on the transform plane because of the Phase conjugation effeCt inside the crystal,so that the edge enhancing image is obatined on the image plane at last. Experimeatal results and brief theoretical analysis are presented in this peper.
