摘要
图像增强技术在工业、国防和科学研究等部门都有重要的应用，其中用光学方法实现图像增强更具有它独特的优点。自激光出现以后，人们便把它作为一种理想光源。
In this article, an improved method of image edge enhancement is presented. Compared with that method described in literature[6], this one does not need two-exposure, turning grating and replacing spatial filter between two-exposures. Thus, operational process is simplified greatly.
