用云纹法获取面内静位移场的实验研究

STUDY TO OBTAIN STATIC DISPLACEMENTFIELD OF IN-PLANE BY MOIRE METHOD

本文采用４０线／ｍｍ的单线栅和正交栅分别获取面内静位移场：并在富里叶光学空间滤波系统中，用白光光源替代激光光源，对正交位移场实现ｕ、ｖ场的条纹分离；

おn this paper,we used linear grating and perpendicular gration (40 1/mm) to obtain static displacement fields of in -plangIn optical spatial filtering system,laser is replaced by white light,the moire fringes of perpendicular displacement field are resolved,some experiment techniques are studied and discussed
