提出了一种基于部分相干照明的单光束相位恢复方法。通过使用正逆迭代（ORI）算法，可以在更短的时间内重建物体，通过记录在不同的轴平面的衍射图案的序列在部分相干光照明下。部分相干光照明减少了相干噪声和重建所需的衍射图案的数量。因此，整个过程是快速的，并且由于无参考配置而具有对外部扰动的高免疫力。仿真和实验结果证明了该方法的可行性。
A single-beam phase retrieval method with partially coherent illumination is proposed. By using an obverse and reverse iterative (ORI) algorithm, objects can be reconstructed within less time by recording a sequence of diffraction patterns at different axial planes under partially coherent light illumination. Partially coherent light illumination reduces coherent noise and the number of diffraction patterns needed for reconstruction. Thus, the whole process is fast and has high immunity to external perturbation due to the reference-less configuration. Both simulation and experimental results are presented to demonstrate the feasibility of the proposed approach.
