摘要
提出用量子散射理论研究X射线波段的新型元件——Bragg-Fresnel元件,并对该元件的设计原理作了详细推导.用矩形函数表述了线性Bragg-Fresnel元件的衍射图形模式并编制了数值化计算机程序系统对其进行设计.最后给出线性Bragg-Fresnel元件的整体设计结果.
In this paper, a quantum scattering theory is given to calculate the performances of the X- ray multilayer Bragg- Fresnel lens recently developed for X- ray optics. The scattering amplitude, diffraction pattern, diffraction efficiency and scattered power density are derived. A computer program worked out by the authors is introduced and the design of Bragg-Fresnel optics is also given.
