Abstract: A method and system for use in reconstruction and retrieval of phase information associated with a two-dimensional diffractive response are presented. The method comprising: providing (75) input data indicative of one or more diffractive patterns corresponding to diffractive responses from one or more objects (50). Dividing (130) said input data into a plurality of one-dimensional slices and determining (140) one-dimensional phase data for at least some of said one-dimensional slices. Tailoring (150) the reconstructed phase data of said one-dimensional slices to form a two-dimensional phase solution. The two-dimensional phase solution is defined by phase shifts of said reconstructed one-dimensional phase data of said one-dimensional slices. The two-dimensional phase solution thus enables obtaining two-dimensional reconstructed phase data suitable for reconstruction of image data (250).
