Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry. In principle, it is possible to make a hologram for any type of wave.
Dennis Gabor was a Hungarian-British electrical engineer and physicist, most notable for inventing holography, for which he later received the 1971 Nobel Prize in Physics. He obtained British citizenship in 1934, and spent most of his life in England.
The Holodeck is a fictional device from the television franchise Star Trek which uses "holograms" to create a realistic 3D simulation of a real or imaginary setting, in which participants can freely interact with the environment as well as objects and characters, and sometimes a predefined narrative.
Holographic data storage is a potential technology in the area of high-capacity data storage. While magnetic and optical data storage devices rely on individual bits being stored as distinct magnetic or optical changes on the surface of the recording medium, holographic data storage records information throughout the volume of the medium and is capable of recording multiple images in the same area utilizing light at different angles.
Holographic interferometry (HI) is a technique which enables the measurements of static and dynamic displacements of objects with optically rough surfaces at optical interferometric precision. These measurements can be applied to stress, strain and vibration analysis, as well as to non-destructive testing and radiation dosimetry. It can also be used to detect optical path length variations in transparent media, which enables, for example, fluid flow to be visualised and analyzed. It can also be used to generate contours representing the form of the surface.
Digital holography is the acquisition and processing of holograms with a digital sensor array, typically a CCD camera or a similar device. Image rendering, or reconstruction of object data is performed numerically from digitized interferograms. Digital holography offers a means of measuring optical phase data and typically delivers three-dimensional surface or optical thickness images. Several recording and processing schemes have been developed to assess optical wave characteristics such as amplitude, phase, and polarization state, which make digital holography a very powerful method for metrology applications .
Computer-generated holography (CGH) is a technique that uses computer algorithms to generate holograms. It involves generating holographic interference patterns. A computer-generated hologram can be displayed on a dynamic holographic display, or it can be printed onto a mask or film using lithography. When a hologram is printed onto a mask or film, it is then illuminated by a coherent light source to display the holographic images.
Stephen Anthony Benton was the inventor of the rainbow hologram and a pioneer in medical imaging and fine arts holography. Benton held 14 patents in optical physics and photography, and taught media arts and sciences at Massachusetts Institute of Technology (MIT). He was the E. Rudge ('48) and Nancy Allen Professor of Media & Sciences, and the Director for Center for Advanced Visual Studies (CAVS) at MIT.
Australian Holographics was a laboratory based in Adelaide, South Australia. It was established in 1989 with the specific objective to produce high quality large format holograms. After two years of research and development, the company began commercial operations in 1991. The laboratory eventually shut down in 1998.
Zebra Imaging was a company that developed 3D digital holographic images, hologram imagers and interactive 3D displays for government and commercial uses. The company offers digital holograms that are autostereoscopic, full-parallax and in monochrome or full-color. They have also developed a 3D Dynamic Display, which is capable of rendering holograms in real time; design work with 3D programs such as SketchUp and 123D Catch can be viewed on a holographic display while they are actively being edited.
The EDAPS Consortium was a consortium which manufactured identification documents and information systems. It was founded in Kyiv in 2004 by eight leading Ukrainian security printing and information technology companies. In December 2016, the consortium was dissolved in view of the fact that it was a temporary association of companies in the first place and that the common goals to be achieved by its participants have been achieved.
Specialized Enterprise Holography Ltd. (SE Holography) is a company that specializes in production of holograms and holographic security elements. Holography, a member-company of the EDAPS Consortium, is among the founders of the security printing industry in Ukraine. Established in 2000 with the support of the International Centre the Institute of Applied Optics on behalf of the National Academy of Sciences of Ukraine. Holography Ltd. is a member of the International Hologram Manufacturers Association (IHMA), a member of the International Society for Optical Engineering (SPIE) and a member of the Counterfeiting Intelligence Bureau at the International Chamber of Commerce of Ukraine.
Yves Gentet is a French engineer and artist, known for the invention of a creative method of holograms in colour Ultimate and a 3D holographic printer Chimera.
A holographic weapon sight or holographic diffraction sight is a non-magnifying gunsight that allows the user to look through a glass optical window and see a holographic reticle image superimposed at a distance on the field of view. The hologram of the reticle is built into the window and is illuminated by a laser diode.
Functional Holography (FH) is a method of analysis designed to extract the maximum amount of functional information about the dynamical network as a whole unit.
Juris Upatnieks is a Latvian-American physicist and inventor, and pioneer in the field of holography.
Wenyon & Gamble is the name used by the art team of Susan Gamble and Michael Wenyon.
Windows Mixed Reality (WMR) is a discontinued platform by Microsoft which provides augmented reality and virtual reality experiences with compatible head-mounted displays.
Tung Hon Jeong was an international leader in the field of holography. He worked with Hans Bjelkhagen on technology to make true-color holograms and assisted in the development of the three-dimensional moving holograms. His research led to simple and economical holograms.
Alex Kipman is a Brazilian engineer. He was the lead developer of the Microsoft HoloLens smartglasses and helped develop the Xbox Kinect.
