optical diffraction
41diffraction grating — /dəˈfrækʃən ˌgreɪtɪŋ/ (say duh frakshuhn .grayting) noun a band of equidistant parallel lines (from 4000 to 12 000 or more to the centimetre), ruled on a surface of glass or polished metal, used for obtaining optical spectra …
42Near-field scanning optical microscope — Near field scanning optical microscopy (NSOM/SNOM) is a microscopic technique for nanostructure investigation that breaks the far field resolution limit by exploiting the properties of evanescent waves. This is done by placing the detector very… …
43List of optical topics — Probably some Wikipedia articles on topics in optics are not yet listed on this page. If you cannot find the topic you are interested in on this page, the article may nonetheless exist; you can try to find it using the Search box, or look in and… …
44Fresnel diffraction — In optics, the Fresnel diffraction equation for near field diffraction, is an approximation of Kirchhoff Fresnel diffraction that can be applied to the propagation of waves in the near field.[1] The near field can be specified by the Fresnel… …
45Dynamical 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… …
46Reflection 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… …
47Halo (optical phenomenon) — A halo (unicode|ἅλως; also known as a nimbus, icebow or Gloriole) is an optical phenomenon that appears near or around the Sun or Moon, and sometimes near other strong light sources such as street lights. There are many types of optical halos,… …
48Corona (optical phenomenon) — For other uses, see Corona (disambiguation). A lunar corona …
493D optical data storage — is the term given to any form of optical data storage in which information can be recorded and/or read with three dimensional resolution (as opposed to the two dimensional resolution afforded, for example, by CD). [ Three Dimensional Optical Data …
50Ultra Density Optical — (UDO) is an optical disc format designed for high density storage of high definition video and data. Overview An Ultra Density Optical disc or UDO is a 133.35 mm (5.25 ) ISO cartridge optical disc which can store up to 60 GB of… …
