Research progress in position error correction for scanning coherent diffractive imaging
摘要
Abstract
As an implementation approach for coherent diffraction imaging(CDI)technology,scanning coherent diffraction imaging(SCDI)has partially overcome the limitations of traditional CDI algorithms,such as slow convergence rate,reconstruction stagnation,and non-unique reconstruction solutions.However,it still suffers from inherent drawbacks and challenges,including position errors,noise interference,incomplete source coherence,and long imaging duration.Among these issues,position errors,which are unique to SCDI compared with other microscopic imaging techniques,significantly degrade the final imaging quality.Focusing on this critical factor,this paper first presents the research background of SCDI and summarizes various factors affecting reconstruction quality.Subsequently,it elaborates on position error correction methods in the imaging workflow,the application of deep learning in this field,and various evaluation methods for error correction performance.Finally,this paper summarizes the current progress and prospects the future development trends.This work provides a reference for exploring imaging quality improvement methods of SCDI,and is of important guiding significance for its applications in X-ray imaging.关键词
