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
Diffraction — Computer generated intensity pattern formed on a screen by diffraction from a square aperture … 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 standard — In crystallography, a diffraction standard, or calibration crystal, is a crystal used to calibrate an X ray spectrometer to an absolute X ray energy scale. Quartz or silicon crystals are typically used. There are also reports of crystals of… … Wikipedia
Dynamical theory of diffraction — The dynamical theory of diffraction describes the interaction of waves with a regular lattice. The wave fields traditionally described are X rays, neutrons or electrons and the regular lattice, atomic crystal structures or nanometer scaled multi… … Wikipedia
Powder diffraction — is a scientific technique using X ray, neutron, or electron diffraction on powder or microcrystalline samples for structural characterization of materials. [B.D. Cullity Elements of X ray Diffraction Addison Wesley Mass. 1978] Explanation Ideally … 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
Coherent diffraction imaging — A diffraction pattern of a gold nanocrystal formed from using a nano area beam of coherent X rays. This reciprocal space diffraction image was taken by Ian Robinson s Group to be used in the reconstruction of a real space coherent x ray… … Wikipedia
Electron diffraction — is a technique used to study matter by firing electrons at a sample and observing the resulting interference pattern. This phenomenon occurs due to the wave particle duality, which states that a particle of matter (in this case the incident… … Wikipedia
Modified Bragg diffraction in quasicrystals — It is commonly assumed that diffraction in quasicrystals, whether of electrons, of x rays or of neutrons, is Bragg diffraction. Though there are similarities, notably scattering from atomic planes, there are also contrasting differences [ A.J.… … Wikipedia
electron diffraction — Physics. the phenomenon whereby electron waves scattered by the regularly spaced atoms of a crystal produce diffraction patterns characteristic of the crystal structure and the wavelength. [1925 30] * * * ▪ physics interference effects… … Universalium
