X射线波带片的应用及制备

The Application and Fabrication of X-Ray Zone Plate

随着新一代同步辐射大科学装置的出现,获得高品质X射线光源成为可能,X射线显微成像技术广泛应用于材料科学、生命科学、环境科学等领域。波带片作为X射线显微成像系统中聚焦与成像的核心元件,其制备和性能提高方法越来越受到研究人员的关注。本文介绍了波带片的基本概念、主要类型和应用领域,在此基础上综述了国内外在波带片制备方面的研究现状和最新进展,在总结波带片技术瓶颈的基础上,指出了利用多层薄膜切片法是制备硬X射线波带片的理想方法,我国亟待开展相关研究。

With the emergence of a new generation of synchrotron radiation science devices,it is possible to obtain high-quality X-ray light sources.X-ray microscopic imaging technology is widely used in material science,life science,environmental science and other fields.As the core element of fo-cusing and imaging in X-ray microscopic imaging system,Fresnel Zone Plate(FZP)has attracted more and more attention in the methods of preparation and performance improvement.In this paper,the basic concepts,main types and application fields of FZP are introduced.Based on these,the current research and progress in the fabrication of FZP at home and abroad are reviewed.Fi-nally,the bottleneck of the development of FZP is summarized.It is pointed out that the multilay-er-film-slicing method is ideal for the preparation of hard X-ray FZP.And the relevant research is urgently carried out in our country.
