摘要：
The precision of phase shifting speckle interferometry is investigated by considering the case of a polarising Mach Zehnder interferometer. A theoretical evaluation of the accuracy of the method is carried out by considering the analysis of each component of the interferometer. The random fluctuations of the measurement, which are part of the confidence level that includes the repeatability, are experimentally estimated using a simple twin filtering technique. Quantitative results are reported in the case of a crushing test applied on components encountered in the aeronautics field.
