Abstract :
The proposed modification of an interference signals´ analysis method in PSI stable to a distortion of an interference fringes profile. In the proposed method a phase difference is measured between several selected points on an interference pattern. The method can be used for an analysis interferograms obtained in multipass interferometers.
