A simple analytical approach to phase space analysis of the performance of x-ray optical setups (beamlines) combining several elements in position-angle-wavelength space is presented. The mathematical description of a large class of optical elements commonly used on synchrotron beamlines has been reviewed and extended with respect to the existing literature and is reported in a revised form. Novel features are introduced, in particular, the possibility to account for imperfections on mirror surfaces and to incorporate nanofocusing devices like refractive lenses in advanced beamline setups using the same analytical framework. Phase space analysis results of the simulation of an undulator beamline with focusing optics at the European Synchrotron Radiation Facility compare favorably with results obtained by geometric ray-tracing methods and, more importantly, with experimental measurements. This approach has been implemented into a simple and easy-to-use program toolkit for optical calculations based on the Mathematica software package.
提出了一种简单的分析方法，用于在位置 - 角度 - 波长空间中对组合多个元件的X射线光学装置（光束线）的性能进行相空间分析。相对于现有文献，对同步辐射光束线上常用的一大类光学元件的数学描述进行了回顾和扩展，并以修订形式进行了报道。引入了新的特性，特别是在使用相同分析框架的先进光束线设置中，考虑镜面缺陷以及纳入诸如折射透镜等纳米聚焦装置的可能性。欧洲同步辐射设施中具有聚焦光学元件的波荡器光束线模拟的相空间分析结果，与通过几何射线追踪方法获得的结果相比具有优势，更重要的是，与实验测量结果相比也是如此。这种方法已被实现为一个基于Mathematica软件包的简单易用的光学计算程序工具包。
