光栅成像反射莫尔干涉术

利用光栅成像效应可构成一种光栅成像反射干涉仪。配合莫尔技术,在自成像平面可获得表征镜状表面试件离面位移一阶偏导等值线的反射莫尔条纹。并给出了这种干涉术的理论分析及实验例证。

Grating imaging reflection Moire interferometry

By using grating imaging effect, a grating imaging reflection interferometer can be formen. Combining Moire method, reflection moire fringes which represent partial slope contours of out-of plane displacement of a mirrored surface specimen will be gotten on the self imaging plane of the interferometer.Comparing with conventional reflection moire method, this new method is a real time one and it no longer needs a high quality camera refqired by the conventional method. Both theoretical analyses and experimental vesults are presented.
