Abstract

Dynamic speckle pattern interferometry has been widely applied to measure vibration or continuously-deformation. As a promising technique, temporal phase analysis reduces the 2D phase retrieval task to 1D and gives wider measurement range. In this paper, some classical and recently proposed temporal phase retrieval techniques, such as windowed Fourier transform, wavelet transform and Hilbert transform, are comparatively studied. The advantages and drawbacks of each algorithm are discussed and evaluated in simulation experiments.
