在X射线衍射领域，多层膜光学是一种应用广泛的X射线光束调节光学。多层光学器件提供了良好的平衡性能。采用多层膜光学器件调节后的光束具有发散角小、光谱纯度好、光强高的特点。本文首先简要回顾了X射线多层膜的发展历史，总结了X射线多层膜的基本性能特点，然后讨论了一维和二维光学系统的设计原理。平行光束光学和聚焦光学都将得到解决。作为例子，多层膜光学的选定应用也作了简要讨论。最后，指出了多层膜光学应用中存在的主要问题，并对未来的发展进行了展望。
Multilayer optics is one of the widely applied optics for conditioning an X-ray beam in the region of X-ray diffraction. Multilayer optics offers a well-balanced performance. The beam conditioned by a multilayer optic is characterized by low divergence, good spectrum purity, and high intensity. This article will start with a short historical note of the development of X-ray multilayer and a summary on the basic performance characteristics of X-ray multilayer, then move on to the discussion on the design principle of one- and two-dimensional optics. Both parallel beam optics and focusing optics will be addressed. As examples, selected applications of multilayer optics are also briefly discussed. Finally, the main problems associated with the application of multilayer optics are identified and the future developments are discussed.
