二维相移逻辑云纹法──条纹图全自动处理的一种方法

Two Dimensional Phase Shift and Logical Moire──A fast and automatic method for whole field fringe pattern analysis

本文报告的二维相移逻辑云纹法，可对二维全场条纹图，进行全自动处理。这种方法用了经典云纹的概念，运用了相移的思想，用计算机进行逻辑运算，从而获得了全场条纹图上任意点的信息，为后续的运算提供了方便。这种方法可用于若干种条纹图的处理。

In this paper, two--dimensional phase shift and logical moire method is reported.It is an automatic and fast method to analize a whole field fringe Pattern. In this method the conception of classical moire, Phase shifting method and logical calculation are used to extract the information at any point of the fringe Pattern by computer. This method can be used to fringe Processing in wide areas.
