Coherent diffraction imaging and lens position correction by a transversely moving lens

We introduce what we believe is a novel approach for wavefront reconstruction by a laterally moving lens, in conjunction with amplitude-phase retrieval. Compared to axial multiple-image phase retrieval methods, the proposed lateral methodology exhibits superiority of accuracy. To minimize the effect of position error of lens, we have also developed error models and associated corrective strategies, which may offer valuable guidance for determining axial and lateral errors in optical systems. Furthermore, our investigation reveals that phase conveys crucial information concerning beam propagation, thus playing a significant role in both phase retrieval and lateral error correction. Our experimental outcomes demonstrate the efficacy of our proposed techniques in obtaining the amplitude and phase information of the sample.
