Abstract

Dynamic speckle interferometry using temporal phase analysis has larger measurement range and is easier to setup over phase-shifting based speckle interferometry. Hilbert transform (HT) is a widely used approach to implement analytic method based phase retrieval. To fulfill the requirements of HT based phase retrieval, EMD (Empirical Mode Decomposition) can be applied to remove the bias intensity. With the low noise assumption, the first IMF was taken as the input for HT. However, according to our experiments, some dynamic speckle signals are not as good as assumed. In many cases, the first IMF is not the proper one. To find the proper IMF, we proposed to adaptively find the IMF of largest similarity with the input signal. And the similarity is evaluated by mutual information. Simulation experiments were given to verify the validity of the proposed algorithm.
