Analysis of Factors Affecting Ptychographical Intensity Interferometry Imaging

Intensity interferometry (II), as a lensless imaging technique, has the advantages of high resolution. However, the phase retrieval algorithm has the defect of unstable convergence, which leads to partial optimization of II. The introduction of ptychographical into II is considered to overcome this shortcoming, namely ptychographical intensity interferometry imaging (PIII). In this paper, we studied the factors that affect PIII through simulation demonstrations, and the results show that the increase of speckles, overlap and iterations can effectively improve the quality of PIII. This result has guiding significance for the subsequent application of PIII in the field of optics.
