Abstract

Coherent diffraction imaging(CDI) is a lensless imaging technology that can achieve an accuracy higher than the resolution limit. Improving the accuracy of simulation results for diffraction is of great significance for the development of coherent diffraction imaging technology. In this work, a method to calculate the intensity distribution of diffraction light for certain given objects will be illustrated, which is not based on the Fourier transform algorithm. This method can achieve simulation results closer to actual experiment results, while it will be more time-consuming. Five different objects are selected to calculate intensity distribution of diffraction light on different record planes, with various ranges of pointing stability.500 simulation results are achieved in total. The influence from pointing stability on simulation results of intensity distribution of diffraction light is analysed and illustrated.
