论文摘要

本章介绍了基于龙虾眼设计的大型视野X射线光学领域的历史,原理和最新发展。大多数在天文学和其他应用中使用的放牧发病率(反射性)X射线成像系统基于Wolter 1(或修改)的布置。但是,对于实验室和空间环境的将来的应用程序也提出了其他设计和配置。基于Kirkpatrick-baez(K-B)镜头以及各种类型的龙虾眼镜作为一个例子。所有这些系统都类似于沃尔特镜头,使用的原理是X射线被两次反映以创建焦点图像。 X射线天文学和天体物理学的各种未来项目将需要大量的光学器件,并具有广泛的视野。大型Kirkpatrick-Baez模块和龙虾眼X射线望远镜都可以用作解决方案,因为这些望远镜可以提供诸如广泛的视野,低质量和降低成本的创新。讨论了使用微孔光学元件(MPO)及其各种用途的龙虾眼镜的基本起作用。评估了这些光学的问题和限制因素,并审查了使用龙虾眼光来实现其科学目标的当前任务。多箔光学(MFO)方法代表了一个有希望的替代方案。这些布置也可以广泛应用于实验室设备。本章还研究了其他科学领域的非沃特系统的替代应用的详细信息,其中其中一些已经证明了它们的优势,例如K-B系统已经在实验室和同步物中发现了广泛的应用。

This chapter describes the history, principles, and recent developments of large field of view X-ray optics based on lobster eye designs. Most of grazing incidence (reflective) X-ray imaging systems used in astronomy and other applications, are based on the Wolter 1 (or modified) arrangement. But there are also other designs and configurations proposed for future applications for both laboratory and space environments. Kirkpatrick-Baez (K-B) based lenses as well as various types of lobster eye optics serve as an example. Analogously to Wolter lenses, all these systems use the principle that the X-rays are reflected twice to create focal images. Various future projects in X-ray astronomy and astrophysics will require large optics with wide fields of view. Both large Kirkpatrick-Baez modules and lobster eye X-ray telescopes may serve as solutions as these can offer innovations such as wide fields of view, low mass and reduced costs. The basic workings of lobster eye optics using Micro Pore Optics (MPOs) and their various uses are discussed. The issues and limiting factors of these optics are evaluated and current missions using lobster eye optics to fulfil their science objectives are reviewed. The Multi Foil Optics (MFO) approach represents a promising alternative. These arrangements can also be widely applied in laboratory devices. The chapter also examines the details of alternative applications for non-Wolter systems in other areas of science, where some of these systems have already demonstrated their advantages such as the K-B systems which have already found wide applications in laboratories and synchrotrons.
