摘      要：Based on the recently developed ptychographical iterative engine(PIE),we suggest a lens assisted microscopy to realize quantitative phase imaging without using *** sample is imaged with a lens system;a pinhole on the image plane scans the image at a proper step interval;the diffraction pattern is recorded simultaneously by a CCD at Fresnel *** a slightly changed PIE algorithm,the phase image of the sample can be accurately reconstructed from the recorded diffraction *** main advantage of this suggested method lies in its capability to retrieve the phase information from the recorded intensity directly,and thus it has more flexibility over conventional interferometric *** feasibility of the suggested method is verified by reconstructing the modulus and phase image of a biological sample from a set of 10 by 10 diffraction patterns,and the result matches the analysis well.
