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. © 2012 Optical Society of America.||Source Title:||Journal of the Optical Society of America A: Optics and Image Science, and Vision||URI:||http://scholarbank.nus.edu.sg/handle/10635/56076||ISSN:||10847529||DOI:||10.1364/JOSAA.29.000585|
