Small-angle neutron scattering — (SANS) is a laboratory technique, similar to the often complementary techniques of small angle X ray scattering (SAXS) and light scattering. These are particularly useful because of the dramatic increase in forward scattering that occurs at phase … Wikipedia
Biological small-angle scattering — Small angle scattering is a fundamental method for structure analysis of materials, including biological materials. Small angle scattering allows one to study the structure of a variety of objects such as solutions of biological macromolecules,… … Wikipedia
Grazing-incidence small-angle X-ray scattering — (GISAXS) is a scattering technique most commonly done at synchrotron radiation facilities. A related technique also exists for neutron scattering (GISANS). 300px|thumb|right|Scheme 1: GISAXS scattering geometry. The incident beam strikes the… … Wikipedia
Diffraction topography — (short: topography ) is an X ray imaging technique based on Bragg diffraction. Diffraction topographic images ( topographs ) record the intensity profile of a beam of X rays (or, sometimes, neutrons) diffracted by a crystal. A topograph thus… … Wikipedia
Angle of incidence — is a measure of deviation of something from straight on , for example: in the approach of a ray to a surface, or the angle at which the wing or horizontal tail of an airplane is installed on the fuselage, measured relative to the axis of the… … Wikipedia

Diffraction grating — A very large reflecting diffraction grating. In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. The directions of these beams … Wikipedia
Diffraction-limited system — Memorial to Ernst Karl Abbe, who approximated the diffraction limit of a microscope as , where d is the resolvable feature size, λ is the wavelength of light, n is the index of refraction of the medium being imaged in, and θ (depicted as α in the … Wikipedia
Reflection high energy electron diffraction — (RHEED) is a technique used to characterize the surface of crystalline materials. RHEED systems gather information only from the surface layer of the sample, which distinguishes RHEED from other materials characterization methods that rely also… … Wikipedia
Fiber diffraction — is an important simplification of the general scattering technique in which molecular structure is determined from scattering data (usually of X rays, electrons or neutrons). In fiber diffraction the scattering pattern does not change, as the… … Wikipedia
