Abstract

The electronic speckle pattern interferometry (ESPI) is one of the important optical measurement methods. The extracting information of the ESPI fringes is one of the key technologies during ESPI application. A fringe center method for ESPI interferogram analysis and a method based on the fringe refinement algorithm are introduced. The thin skeletons are amending to be smooth. The method can automatically pick up the fringe skeletons. A measurement experiment by using this technique is used to detect and analyze the deformation of the sample. The result is in agreement with the actual situation.
