Paper Abstract

The Gerschberg-Saxton (GS) algorithm is a classic algorithm for phase retrieval. It is usually based on FFT (fast Fourier transform) and IFFT (inverse fast Fourier transform). We improve the GS algorithm based on the Wigner distribution. Instead of FFT and IFFT, Wigner distribution is not only used in the propagation but also filtered to optimize the signal during the iteration. The simulation results illustrate that the new method could effectively improve the efficiency and accuracy of phase retrieval.
