A genuine representation of the cross-spectral density function as a superposition of mutually uncorrelated, spatially localized modes is applied to model the propagation of spatially partially coherent light beams in X-ray optical systems. Numerical illustrations based on mode propagation with VirtualLab software are presented for imaging systems with ideal and non-ideal grazing-incidence mirrors.
将互不相干、空间局域化模式叠加的交叉谱密度函数的真实表示应用于对X射线光学系统中空间部分相干光束的传播进行建模。针对具有理想和非理想掠入射镜的成像系统，给出了基于VirtualLab软件模式传播的数值示例。
