    One of the limitation of speckle correlation interferometric techniques including shearography is that the rigid Any motion yields decorrelation of speckle patterns before and after deformation which results in the deterioration of fringe visibility. This peper proposes a method which can effectively tolerate rigid they motion. It involves rearranging the recorded speckles before and after deformation in order to enlarge the speckle size, averaging speckles to improve the quality of fringe Patterns, and reconstructing fringe patterns and iteration of smooth to further suppress the speckle noise to obtain decent result.
