We propose a novel approach based on a 3D directional wavelet transform to retrieve optical phase distributions in temporal speckle pattern interferometry. We show that this approach can effectively recover phase distributions in time series of speckle interferograms which are affected by sets of adjacent non-modulated pixels. The performance of this phase retrieval approach is analyzed by introducing a temporal carrier in the out-of-plane interferometer setup, and assuming modulation loss and noise effects. The advantages and limitations of this approach are finally discussed.
