摘　　要：上海光源是第三代同步辐射光源,其X射线成像具有高空间分辨、快时间分辨、高衬度分辨的特点,可对材料样品实现原位、无损、高分辨、三维和动态成像,利用同步辐射光源的高度相干性可以实现相位衬度成像,从而可以实现聚合物等低Z材料的高衬度X射线成像,而传统的X射线吸收衬度成像在对轻元素材料成像上获得的衬度极低。为更好地支持用户,基于上海光源X射线成像线站,建立和发展了定量相衬成像、动态CT成像、基于多种衬度机制的CT成像、快速CT重构等成像方法。本文简要介绍了上海光源X射线成像方法学发展及其在材料科学上的应用研究进展。Shanghai synchrotron radiation facility(SSRF)is the third generation of synchrotron radiation facility.X-ray imaging at SSRF has the characteristics of high spatial resolution,fast temporal resolution and high contrast resolution and can realize in-situ,non-destructive,high-resolution,three-dimensional and dynamic imaging of material samples.Using the high coherence of synchrotron radiation light source,X-ray phase-contrast imaging can be realized with high contrast for low-Z materials such as polymers.Traditional X-ray absorption-contrast imaging can obtain low contrast for light element materials.In order to better support users,based on X ray imaging beamline at SSRF,quantitative phase-contrast imaging,dynamic CT imaging,CT imaging based on multiple contrast mechanisms,fast CT reconstruction and other imaging methods have been established and developed.This paper introduces the development of X-ray imaging methodology and its application in material science of X-ray imaging beamline at SSRF.
