Abstract
We compare the performance of various recently-developed phase recovery approaches when they are applied in temporal speckle pattern interferometry. The phase retrieval methods to be evaluated are based on the 1D continuous wavelet, the Hilbert-Huang and the S-transforms, and the smooth time-frequency distribution. It is shown that the 3D directional wavelet transform approach outperforms the use of these 1D phase recovery techniques when sets of adjacent non-modulating pixels, modulation loss and noise effects are present in the recorded data.
