| 摘 要： | 光学图像微分（边缘增强）是光学信息处理中突出信息的一种重要方法。本文介绍了全息复合光栅和光学子波变换在实现图像边缘增强中的应用，并进行了实验研究和原理分析。实验结果表明这两种方法都是实现图像边缘增强的有效方法，相比较而言，光学子波变换更为快速和实用。

| Abstract: | Optical image differentiation (edge extraction) is an important method of stand out the information in optical image processing. This paper presents the application of composite holographic grating and optical wavelet transform to image edge extraction, and makes experiments and theoretical analysis. The experimental results show both of methods are effective, but real-time wavelet transform is more practicable. |
