title: An iterative phase retrieval algorithm for in-line x-ray phase imaging.
abstract: A general theoretical formulism for in-line phase x-ray imaging was presented with a corresponding linear formula in previous works. In this report, an iterative approach is introduced for phase retrieval with a nonlinear formula. The results of simulation showed that the iterative approach can retrieve the phase map more effectively with high efficiency and flexibility.
