Paper Abstract

In this letter, we propose a novel method to quantitatively recover a complex-valued object from diffraction intensity maps. A wavefront modulation is introduced in the optical path, and several diffraction intensity maps are recorded through position shift of a phase mask. A phase retrieval algorithm is further developed, and advantages of the proposed method are discussed.
