Phase Retrieval Using the Transport-of-Intensity Equation
The transport-of-intensity equation describes the internal relationship between the intensity and phase distribution while wave is propagating in the mobile space. So the phase distribution can be solved by the use of the equation. It is an important measurement of non-interferometry. A new phase retrieval based on transport-of-intensity equation is presented. This method has the advantage of measuring only the closeup space on the plane of the intensity of light to the reconstruction of phase space. The problem of phase retrieval is translated into minimum of energy functional with linear convolution and total variation regularization. The one and two dimension experiment results show the correctness and validity of the algorithm.
