相移云纹干涉系统及其应用

摘要

In this paper, a high precision and automaticmethod--phase shift moir'e interferometry has beendeveloped. The displacement and strain fields in theinterface region of bimaterial are determined using thismethod. Experimental results show that in the interfaceregion the shear strain exhibits a high gradient.%将云纹干涉法和相移技术结合起来，实现了基于Carr'e算法的相移云纹干涉系统，测量精度可以达到纳米量级而且提高了测试自动化程度；并将其应用于双材料的界面力学问题研究.
