| Abstract: | In this paper, the geometric center and centroid method are suggested to trace center location of a close fringe pattern. The fringe pattern of the interferogram is analysed by using the general Fourier method. The analytic accuracy is controlled by using P-test method of statistics. The analytic accuracy and sampling speed of the fringe pattern depend on the quality of the interferogram and the numbers of the sampling points. |
