摘要
讨论了小波变换的光学实现方法，选择Ｍｅｘｉｃａｎ－ｈａｔ小波对光学信号提取进行了数值模拟，发现Ｍｅｘｉｃａｎ－ｈａｔ小波在信号提取方面的缺陷，在此基础上，提出了一种新的小波，并进行了数值模拟。
In this paper we discuss the realization of an optical wavelet transform. While choosing the Mexican hat wavelet to extract an optical signal by computer simulation, we find the defect of this wavelet in signal extraction. Base on this finding, we put forward a new wavelet and its merits have been testified by computer simulations.
