Examples of this type of depiction include the hologram of Princess Leia in Star Wars, Arnold Rimmer from Red Dwarf, who was later converted to "hard light" to make him solid, and the Holodeck and Emergency Medical Hologram from Star Trek. [1] Holography served as an inspiration for many video games with the science fiction elements.
The hologram keeps the information on the amplitude and phase of the field. Several holograms may keep information about the same distribution of light, emitted to various directions. The numerical analysis of such holograms allows one to emulate large numerical aperture, which, in turn, enables enhancement of the resolution of optical microscopy.
According to The Oxford English Minidictionary, an autograph is, apart from its meaning as a signature, a "manuscript in the author's handwriting," while a holograph is a "(document) written wholly in the handwriting of the person in whose name it appears." [2]
Michael Coleman Talbot (September 29, 1953 – May 27, 1992) [1] was an American author of fiction and non-fiction. He wrote several books highlighting parallels between ancient mysticism and quantum mechanics, and espousing a theoretical model of reality that suggests the physical universe is akin to a hologram based on the research and conclusions of David Bohm and Karl H. Pribram. [2]
A hologram is a recording of a three-dimensional image created by holography. Hologram may also refer to: Hologram, a 2001 EP by Eiko Shimamiya; Hologram, a 2018 EP by Key "Hologram" (Minmi song), 2015 "Hologram" (Nico Touches the Walls song), 2009 "Hologram", a song by Backstreet Boys from This Is Us, 2009
Holograph, a document written entirely in the handwriting of the person who signed it; Holographic principle, a conjecture of quantum gravity; Holographic weapon sight, non-magnifying gun sight; Windows Holographic, augmented reality computing platform; Holographic kinetics, an Aboriginal-based therapy in Alternative medicine
When the hologram plate is illuminated by a laser beam identical to the reference beam which was used to record the hologram, an exact reconstruction of the original object wavefront is obtained. An imaging system (an eye or a camera) located in the reconstructed beam 'sees' exactly the same scene as it would have done when viewing the original.
The hologram is made by measuring acoustic pressure away from the source using an array of transducers (microphones) or a single scanning transducer. The next stage is data processing with a computer. Fourier transforms are used to convert information from the time domain into the frequency domain. A set of intermediate holograms are produced ...
