  • 1949, coined by Hungarian-born British scientist Dennis Gabor (Gábor Dénes), 1971 Nobel prize winner in physics for his work in holography; from Greek holos "whole" (here in sense of "three-dimensional;" see safe (adj.)) + -gram.1949, 1971

Articles from Wikipedia

  • Hologram trademark A hologram trademark is a non-conventional trademark where a hologram is used to perform the trademark function of uniquely identifying the commercial origin of products or services.
  • Hologram (Nico Touches the Walls song) "Hologram" (ホログラム) is the sixth single by the Japanese band Nico Touches the Walls and second from the album Aurora, released on November 25, 2009.
  • Microhologram Microholograms are a technology for moving holographic protection to the level of primary material (substrate).
  • Hologram (Minmi song) "Hologram" is a song recorded by Japanese recording artist Minmi, taken from her seventh studio album Ego (2015). It was made available for digital download and physical consumption on June 10, 2015 through Universal J—a subsidiary label owned by Universal Music Japan—as her third stand-alone single. "Hologram" marks Minmi's second consecutive recording after "Ite Itai yo" to have been written, composed, arranged, and produced by herself. Musically, the song was described by a critic at Selective Hearing as a transition from her signature reggae music styles to electronic dance music, whilst retaining musical elements of dancehall music.
  • A Hologram for the King (film) A Hologram for the King is a 2016 comedy-drama film written, directed and co-scored by Tom Tykwer, based on the 2012 novel of the same name written by Dave Eggers, and starring Tom Hanks as a washed-up corporate salesman, who goes to Saudi Arabia to propose a business deal.
  • Security hologram Security holograms are labels with a hologram printed onto it for sale security reasons. Holograms on security labels are very difficult to forge because they are replicated from a master hologram which requires expensive, specialized and technologically advanced equipment. They are used widely in several banknotes around the world, in particular those that are of high denominations. They are also used in passports, credit and bank cards as well as quality products. Herman Lopata, the President of the New York-based Automatic Toll Systems, Inc., received a patent in 1987 for the credit card security hologram as part of his early work on high speed highway toll collection—the predecessor of the modern EZ Pass type equipment.
  • Jem and the Holograms (film) Jem and the Holograms is a 2015 American musical fantasy comedy-drama film produced and directed by Jon M. Chu, written by Ryan Landels, and starring Aubrey Peeples, Stefanie Scott, Hayley Kiyoko, Aurora Perrineau, Ryan Guzman, Molly Ringwald, and Juliette Lewis. Borrowing elements from the 1980s animated television series Jem by Christy Marx, the film was produced by Hasbro Studios and Blumhouse Productions. Chu's interest in developing a film adaptation of Jem is based on having grown up watching the original animated series with his sisters. He had attempted to make the film 11 years earlier, but was rejected by Universal due to the cost.
  • Hologram (disambiguation) A hologram is a three-dimensional image created by holography.
  • Rainbow hologram The rainbow or Benton hologram is a type of hologram invented in 1968 by Dr. Stephen A. Benton at Polaroid Corporation. Rainbow holograms are designed to be viewed under white light illumination, rather than laser light which was required before this. The rainbow holography recording process uses a horizontal slit to eliminate vertical parallax in the output image, greatly reducing spectral blur while preserving three-dimensionality for most observers. A viewer moving up or down in front of a rainbow hologram sees changing spectral colors rather than different vertical perspectives. Because perspective effects are reproduced along one axis only, the subject will appear variously stretched or squashed when the hologram is not viewed at an optimum distance; this distortion may go unnoticed when there is not much depth, but can be severe when the distance of the subject from the plane of the hologram is very substantial. Stereopsis and horizontal motion parallax, two relatively powerful cues to depth, are preserved.
  • 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 has to have the right wavelength (color) and the wave must have the right shape. Volume holograms are also called thick holograms or Bragg holograms.
