1.引言影象云纹法是实验力学中云纹法的一种。主要用于测量物体表面的离面位移及其型态.该法使用与试件尺寸相当的一块栅板实验法,称为影象云纹法. 影象云纹法的研究在我国近几年才开始.从公开发表的文献看,研究较早的是张世 1. Introduction Image Moire method is a kind of moire method in experimental mechanics. Mainly used to measure the surface of the object from the surface displacement and its type.The method uses a piece of grid plate test method and the size of the specimen, called the image moiré method.Micro image moiré research in our country in recent years Only from the published literature, the earlier study is Zhang Shi
