摘要

A novel in-plane and out-of-plane deformation simultaneous measurement method using only two speckle patterns grabbed before and after deformation of an object with rough surfaces is proposed. An optical system is set up by improving ordinary two-beam speckle interferometer. In the new optical system, because a phenomenon of in-plane and out-of-plane deformation can be simultaneously recorded by only one camera by using the multi-recording method of speckle patterns, the system does not require any alignment of the axes of plural numbers of cameras in new optical system. Therefore, the new method can be readily applied to three dimensional deformation measurement. At the same time, the high resolution measurement of deformation is realized. The validity of the method is discussed by using experimental results in this paper. It is confirmed that the method is useful in the three dimensional deformation measurement of the object with rough surfaces.
