Paper Abstract

Interferometry is a successful method of measuring fields of refractive index and displacement. It therefore has many applications in the measurement of fluid flows, photo elastic stresses, and surface and vibration analysis. The Fourier transform method of interferogram analysis is a useful mean of extracting phase information from linear fringe patterns generated by the interference of tilted wave fronts. This paper introduces Fourier transform method, and the results are given by applying the method to recovery ofthe original wave front in lateral-shearing interferometry.
