Although optical reflexion and refraction of X-rays have been known for more than twenty years, they have so far found only one significant, although very important, application, namely, the spectroscopy of X-rays by means of optical gratings. But there is at least one other problem which should be solved by optical methods: the production of a finely ...

In the past half decade or so there has been a technological revolution in our ability to generate, control, manipulate, focus, and detect x rays. The emergence of x-ray lasers and synchrotron insertion devices has increased the brightness of laboratory x-ray sources 8 to 12 orders of magnitude over what was available in the late 1960s.

Calibration and Metrology of X-Ray Optics at the Center for X-ray Optics
Soft X-Ray Projection Lithography, 1993In the last 20 years x-ray optics has become an important branch of optics which is having more and more impact in a variety of scientific and technological areas. These activities require accurate and reliable calibration and standards facilities to enable scientists and engineers to measure the performance of optical elements and predict the ...

Soon after the discovery of x-rays and their property of constructive interference scattering (diffraction) by solids resulting from the ordered array of atoms forming the solids, it was proposed that man-made (synthetic) layered structures might extend the range of utility of this phenomena into spectral domains not accessible using naturally ...

X-Ray Optics: Imperfections of Optical Flats and Their Effect on the Reflection of X-Rays
Journal of the Optical Society of America, 1949It has been observed that some stray light (x-rays) is thrown into the neighborhood of the focus obtained if x-rays are focused by a bent optical flat. Most of this extra light is due to imperfections of the optical flats, while halation, Fresnel diffraction at the slits and air scattering make only minor contributions.

The X-ray optics for X-ray pulsar navigation
SPIE Proceedings, 2016The effective X-ray optics is a key premise for X-ray pulsar detection and navigation. However, it is very difficult to focus the X-ray photons through refraction for the reason that the X-ray photon is very easy to be absorbed by the materials. The most effective ways for the X-ray focusing is reflection.

Due to the weak interaction of hard x-rays with matter it is generally difficult to manipulate x-rays by optical components. As a result, there have been many complementary approaches to making x-ray optics, exploiting refraction, reflection, and diffraction of x-rays by matter.

Diffraction of x rays in capillary optics
Applied Optics, 2000Propagation of x rays generated by a small-diameter incoherent source through the capillary waveguide that satisfies the multimode condition is studied with the Fresnel-Kirchhoff diffraction theory. The strong influence of diffraction on the propagation is demonstrated.
