摘    要:本文描述了一种新的散斑干涉仪,它可以同时对表面应变物体的面内位移、离面位移、位移梯度和莫尔曲率进行测量;由于利用了取向滤波方法,在滤波系统输出平面同时得到了与这些参数对应的散斑条纹.还利用散斑空间运动规律较好地解释了散斑干涉与散斑剪切干涉之间的关系.

关 键 词:散斑干涉术  散斑剪切干涉  面内位移

Abstract:This paper reports a new speckle interferometer. It can stimultaneonsly determine the in-plane displacement, out-of-plane displacement, slope and moire curvature of the surface strain of object; the fringe patterns are got at the output plane of the filtering system stimultaneously by use of the directional filter, the patterns correspon ing to these quantity. It has been explained that the relation between the speckle interferometry and the speckle shearing interferometry by using the theory of the movement of space speckle.
Keywords:Speckle interferometry  speckle shearing inter-ferometry  in-plane displacement  out-of-plane displacemenb
