The evolution from 3rd to 4th generation of storage rings significantly enhanced the coherence of synchrotron radiation sources, making coherent scattering techniques such as coherent X-ray diffraction imaging (CXDI) and X-ray photon correlation spectroscopy more accessible. In conformance with the design requirements of coherent beamlines at the High Energy Photon Source (HEPS), we have developed wave optics simulation software, the Coherence Analysis Toolbox, based on coherent modes decomposition and a wavefront propagation model. Simulations of beamline performance and a CXDI experiment on the hard X-ray coherent scattering beamline at HEPS were carried out. This software is open source and now available on GitHub.
从第三代到第四代存储环的演进显著提高了同步辐射源的相干性，使得诸如相干X射线衍射成像（CXDI）和X射线光子相关光谱学等相干散射技术更容易实现。根据高能光子源（HEPS）相干光束线的设计要求，我们基于相干模式分解和波前传播模型开发了波光学模拟软件——相干分析工具箱。对HEPS硬X射线相干散射光束线的光束线性能进行了模拟，并开展了CXDI实验。该软件是开源的，目前可在GitHub上获取。
