The phase object is a polypropylene slab into which 3 rings of different depths are engraved. Top left: currently used experimental diffraction patter. Top right: current estimate of the amplitude of the exit wave (the product between the probe function and the object transmission function) at the object plane. Bottom left: current estimate of the reconstructed object amplitude. Bottom right: current estimate of the reconstructed object phase. 2018-01-25 16:23:21 ptychography phase retrieval methods THz imaging Diffraction
