For lens-free imaging technology based on axial multi-plane phase retrieval, the test parameters have a very important impact on the image reconstruction speed and quality. The deviations between the actual position of the recorded diffraction intensity pattern and the set position in the reconstruction algorithm will also affect the image reconstruction quality. We analyzed the influence of test parameters and deviations on the reconstruction accuracy and proposed a method to correct the position mismatch of the intensity image. The effectiveness of the method is verified by simulation and experiment.
