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.
