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.
Hollywood usually refers to:
Evolution is change in heritable traits of biological organisms over successive generations.
Acoustic holography is a technique that allows three-dimensional distributions of sound waves called sound fields to be stored and reconstructed. To do this, sound passing through a surface is recorded as a two-dimensional pattern called a hologram. The hologram contains information about the phase and amplitude of the sound waves passing though. This pattern can be used to reconstruct the entire three-dimensional sound field. Acoustic holography is similar in principle to optical holography.
Holography is a technique for recording and reconstruction of wavefronts.
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.
Nicholas (Nick) John Phillips was an English physicist, notable for the development of photochemical processing techniques for the colour hologram. Holograms typically used to have low signal-to-noise ratios, and Phillips is credited as the pioneer of silver halide holographic processing techniques for producing high-quality reflection holograms.
A holographic display is a type of 3D display that utilizes light diffraction to display a three-dimensional image to the viewer. Holographic displays are distinguished from other forms of 3D displays in that they do not require the viewer to wear any special glasses or use external equipment to be able to see the image, and do not cause a vergence-accommodation conflict.
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.
Specular holography is a technique for making three dimensional imagery by controlling the motion of specular glints on a two-dimensional surface. The image is made of many specularities and has the appearance of a 3D surface-stippling made of dots of light. Unlike conventional wavefront holograms, specular holograms do not depend on wave optics, photographic media, or lasers.
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.
Holography is often used as a plot device in science fiction, appearing in a wide range of books, films, television series, animation and video games. Probably the first reference is by Isaac Asimov in his Foundation series staritng in 1951.
Holographic Studios, located in the borough of Manhattan in New York City, is the world's oldest gallery of holography. It was founded in 1979 by Jason Sapan, one of the pioneers of holography. The storefront level gallery features the world's largest collection of motion image integral holograms. On display in the gallery are a variety of different types of holographic images, including a collection of celebrity hologram portraits. There are also cylindrical 360° floating images, multiple image holograms that change as you walk by, and computer generated holograms as well as a selection of novelty hologram items and stickers. Directly below the gallery is the laser laboratory where holograms are created. Holographic Studios creates custom holograms, holographic portraits, offers classes, and operates tours.
Margaret Benyon,, was a British artist. Trained as a painter, she was one of the first artists to use holography as a medium and had her first solo show of holograms in 1969. She was appointed to the Order of the British Empire in 2000 for her service to art and has been called "the mother of British holography".
