Journal of X-Ray Science and Technology, 1989
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.

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.

Most X-ray optics for use at synchrotron beamlines are structured to achieve a desired performance level. The fabrication steps needed to achieve a certain structure usually limit the final performance, such as for energy resolution and focus size.

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.

X-Ray Optics on a Chip: Guiding X Rays in Curved Channels.
Physical Review Letters, 2015We study the propagation of hard x rays in single curved x-ray waveguide channels and observe waveguide effects down to surprisingly small radii of curvature R≃10 mm and a large contour length s≃5 mm, deflecting beams up to 30°.

X-ray optics of gold nanoparticles
Applied Optics, 2014Gold nanoparticles have been investigated as contrast agents for traditional x-ray medical procedures, utilizing the strong absorption characteristics of the nanoparticles to enhance the contrast of the detected x-ray image. Here we use the Kramers-Kronig relation for complex atomic scattering factors to find the real and imaginary parts of the index ...

Optical Engineering, 1985
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 ...

The British Journal of Radiology, 1929
In the subject of physical optics, or the study of the properties of light waves, a very interesting section deals with the employment of these waves to reveal the shapes of bodies. When a very small body is being examined by a microscope, it is illuminated by light which it scatters in all directions.
