Paper Abstract

The phase distribution of light field at a certain location can be calculated from two close intensities in first-order optical system along the propagation direction, and can be considered as the wavelet transform coefficient of the pupil light field. According to such theory, a new phase retrieval algorithm based on several intensities of different layers is presented in this paper, which can quickly calculate the phase with low frequency, and then gradually increase the resolution by adding more intensity to calculate.
