摘要

阐述了硬X射线光学系统的光线追迹过程

处理的光学系统可包含任意数目的镜子、晶体及光阑

镜子或晶体的面形可以各种各样

它们的排列方式可为共主面或相互正交.根据劳厄衍射方程的矢量形式计算光线经对称或非对称晶体衍射后的方向.我们应用C语言编写了光线追迹程序

它不仅可以得到光路中任意位置像面上光线的点列图分布

而用可以计算晶体的摇摆曲线.最后作为例子

我们用此程序计算了一条同步辐射X射线光束线系统的成像.

Abstract

The raytracing process of an X-ray optical system is described

which may includes any number of mirrors and/or crystals with various figure shapes as well as aperture. The arrangement of optical elements may be coplanar or orthogonal to each other. Diffraction direction of a ray passing a crystal for symmetrical or asymmetrical reflection is calculated from the vector form of Laue diffraction equation. The raytracing program is written in C language

with which not only the ray spot diagram at any position in the optical system can be obtained but also the rocking-curve of a crystal can be calculated. Finally

as an example

the application of the program in calculating the imaging of an X-ray synchrotron radiation beamline system is demonstrated.
