摘　　要：介绍了云纹干涉法及测试原理,给出用于应变检测的计算方法,利用该方法对双光束云纹干涉法获得U,V位移场进行了正应变和切应变计算。表明云纹干涉法对硬质材料的力学参量测试有效,直观,便于应用,能够较好解决力学量的测试工作,为应变检测提供了较好的光学检测方法。Introducing the moire interferometry and its testing theory. Calculating method applied in testing strain is given. Then, normal strain and shear strain of U and V displacement fields obtained four beams moire intefferomentry are calculated according to this calculating method. So it indicates that mechanical parameters of hard materials can be measured by moire interferometry and the testing process is apparently and simply. Through this research working, optical testing method used in measuring strain can be supplied.
