Volume hologram — Volume holograms are holograms where the thickness of the recording material is much larger than the light wavelength used for recording. In this case diffraction of light from the hologram is possible only as Bragg diffraction, i.e., the light… … Wikipedia
Security hologram — 5000/10000 notes, etc. They are also used in credit and bank cards as well as quality products.Holograms are classified into different types with reference to the degree of level of optical security incorporated in them during the process of… … Wikipedia

Holography — (from the Greek, ὅλος hólos whole + γραφή grafē writing, drawing) is a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the… … Wikipedia
Optical vortex — An optical vortex (also known as a screw dislocation or phase singularity) is a zero of an optical field, a point of zero intensity. Research into the properties of vortices has thrived since a comprehensive paper by Nye and Berry, in 1974,[1]… … Wikipedia
Digital holography — is the technology of acquiring and processing holographic measurement data, typically via a CCD camera or a similar device. In particular, this includes the numerical reconstruction of object data from the recorded measurement data, in… … Wikipedia
holography — /heuh log reuh fee/, n. the process or technique of making holograms. [1795 1805; HOLO + GRAPHY] * * * Method of recording or reproducing a three dimensional image, or hologram, by means of a pattern of interference produced using a laser beam.… … Universalium
Zone plate — A zone plate is a device used to focus light. Unlike lenses however, zone plates use diffraction instead of refraction. Created by Augustin Jean Fresnel [freɪ nel] , they are sometimes called Fresnel zone plates in his honor. The zone plate s… … Wikipedia
Polymer banknote — Polymer banknotes were developed by the Reserve Bank of Australia (RBA), Commonwealth Scientific and Industrial Research Organisation (CSIRO) and The University of Melbourne and were first issued as currency in Australia in 1988. These banknotes… … Wikipedia
List of fictional computers — Computers have often been used as fictional objects in literature, movies and in other forms of media. Fictional computers tend to be considerably more sophisticated than anything yet devised in the real world. This is a list of computers that… … Wikipedia
