| Abstract: | The displacement gradient field of a deformed object can be measured with speckle shearing inteferometry. By secondary shearing in the filtering process we obtain second order derivatives. We Propose the principle and experimental demonstration of the method. The method is very simple, fringe quality is fairly good and the information extracted from a specklegram is increased. |
