X-ray optics - Wikipedia
X-ray optics is the branch of optics dealing with X-rays, rather than visible light. It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and X-ray astronomy.
NASA’s New Lightweight X-ray Mirrors Ready for Try-outs in Space
2019年7月29日 · Recent testing has shown that super-thin, lightweight X-ray mirrors made of a material commonly used to make computer chips can meet the stringent imaging requirements of next-generation X-ray observatories.

2012年7月24日 · An X-ray mirror can be made of glass ceramics which is polished to give a very smooth surface (with root-mean-square surface roughness of a few Angstroms) and is coated with metal for X-ray reflection.
How would an X-ray mirror work? - Physics Stack Exchange
2014年7月27日 · How they work is the initial fusion reaction releases high energy radiation, this is then reflected back into the reaction mass increasing the energy levels of the reaction mass causing a sort of radiation implosion. The reflector is typically a cylinder made of a …
Near-100% Bragg reflectivity of X-rays - Nature Photonics
2011年8月21日 · Perhaps one of the most exciting endeavours in physics today is the realization of fully coherent X-ray free-electron lasers (XFEL), and this calls for high-reflectivity X-ray mirrors at...
Nano-precision metrology of X-ray mirrors with laser speckle …
2021年9月22日 · X-ray mirrors are widely used for synchrotron radiation, free-electron lasers, and astronomical telescopes. The short wavelength and grazing incidence impose strict limits on the...
