Abstract

Hybrid Input-Output (HIO) algorithm and its derivatives have been widely used in phase retrieval due to the simple structure and good reconstruction effects. Obtaining accurate knowledge of support constraint is of great significance for HIO algorithm in improving the accuracy and efficiency of reconstruction. We propose a shrink-support algorithm based on the energy concentration in the support domain, which can be combined with HIO algorithm to retrieve the lost phase from a single diffraction intensity pattern without prior knowledge of object shape. Our method is verified in simulation experiments and the reconstruction results show excellent availability.
