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. [1] When a hologram is printed onto a mask or film, it is then illuminated by a coherent light source to display the holographic images.
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.
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.
In video games using procedural world generation, the map seed is a (relatively) short number or text string which is used to procedurally create the game world ("map"). "). This means that while the seed-unique generated map may be many megabytes in size (often generated incrementally and virtually unlimited in potential size), it is possible to reset to the unmodified map, or the unmodified ...
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 purpose of Holus is to simulate holographic experiences and is technically different from typical hologram stickers found on credit cards and currency notes. Holus has been criticized by some commentators as a revamping Pepper's ghost , a 19th-century optical trick.
Electron holography is holography with electron matter waves.It was invented by Dennis Gabor in 1948 when he tried to improve image resolution in electron microscope. [1] The first attempts to perform holography with electron waves were made by Haine and Mulvey in 1952; [2] they recorded holograms of zinc oxide crystals with 60 keV electrons, demonstrating reconstructions with approximately 1 ...
Dejarik is a popular holographic game in the world of Star Wars, installed, for example, on the decks of starships in order to provide entertainment during long flights through hyperspace. A typical game station consists of a hologram generator, usually placed in the cylindrical base of the set, on which there is a board made of three circles ...
