In this paper, we propose effective methods to detect focal planes and recover objects in the noninterferometric phase imaging. A strategy using different aberration coefficients is developed, and a series of diffraction intensity maps is sequentially recorded by a charge-coupled device. During numerical reconstruction, a phase retrieval algorithm is applied to extract object wavefront from diffraction intensity maps. Subsequently, numerical methods are proposed to detect focal planes, and high-quality phase maps are recovered by using the detected focal distances. Theoretical results are presented to demonstrate feasibility and effectiveness of the proposed methods.
