  2. Lobster-eye optics - Wikipedia

    en.wikipedia.org/wiki/Lobster-eye_optics

    Schematic diagram of lobster-eye lens. The green arrow represents the incident light and the red arrows represent the normal of the channel wall. [1]Lobster-eye optics are a biomimetic design, based on the structure of the eyes of a lobster with an ultra wide field of view, used in X-ray optics.

  3. X-ray optics - Wikipedia

    en.wikipedia.org/wiki/X-ray_optics

    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.

  4. Single-shot multi-contrast X-ray imaging - Wikipedia

    en.wikipedia.org/wiki/Single-shot_Multi-contrast...

    Single-shot multi-contrast x-ray imaging is an efficient and a robust x-ray imaging technique which is used to obtain three different and complementary types of information, i.e. absorption, scattering, and phase contrast from a single exposure of x-rays on a detector subsequently utilizing Fourier analysis/technique.

  5. Diffraction topography - Wikipedia

    en.wikipedia.org/wiki/Diffraction_topography

    X-ray diffraction topography is one variant of X-ray imaging, making use of diffraction contrast rather than absorption contrast which is usually used in radiography and computed tomography (CT). Topography is exploited to a lesser extent with neutrons , and is the same concept as dark field imaging in an electron microscope .

  6. X-ray motion analysis - Wikipedia

    en.wikipedia.org/wiki/X-ray_motion_analysis

    X-ray motion analysis is a technique used to track the movement of objects using X-rays.This is done by placing the subject to be imaged in the center of the X-ray beam and recording the motion using an image intensifier and a high-speed camera, allowing for high quality videos sampled many times per second.

  7. Advanced X-Ray Imaging Satellite - Wikipedia

    en.wikipedia.org/wiki/Advanced_X-Ray_Imaging...

    Advanced X-ray Imaging Satellite (AXIS) is a space telescope under development by NASA for launch in 2032. [1] It is a NASA Probe mission concept designed for high angular resolution X-Ray imaging. [2] The mission goals are to examine galaxies over cosmic time, feedback in galaxies, Black Hole strong gravity, Dual AGN, the high redshift universe.

    Tennessee tightened its grip on No. 1 in the AP Top 25 on Monday following a pair of lopsided wins, including one over SEC rival Arkansas, that left the Volunteers as the only undefeated team in ...

  9. Dark-field X-ray microscopy - Wikipedia

    en.wikipedia.org/wiki/Dark-field_X-ray_microscopy

    Dark-field X-ray microscopy (DFXM [1] or DFXRM [2]) is an imaging technique used for multiscale structural characterisation. It is capable of mapping deeply embedded structural elements with nm-resolution using synchrotron X-ray diffraction -based imaging.
