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.
Its flagship device, Microsoft HoloLens, was announced at the "Windows 10: The Next Chapter" press event on January 21, 2015. [2] The HoloLens provides an augmented reality experience where a live presentation of physical real-world elements is incorporated with that of virtual elements (referred to as "holograms" [a] by Microsoft) [3] [4] [5] such that they are perceived to exist together in ...
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.
For holographic data storage, holographic associative memory (HAM) is an information storage and retrieval system based on the principles of holography. Holograms are made by using two beams of light, called a "reference beam" and an "object beam". They produce a pattern on the film that contains them both. Afterwards, by reproducing the ...

Unlike conventional wavefront holograms, specular holograms do not depend on wave optics, photographic media, or lasers. The principle of operation is purely one of geometric optics: A point light source produces a glint on a curved specular (shiny) surface; this glint appears to travel on the surface as the eye or light source moves.
Addressing simultaneously distinct domains of the temporal and spatial bandwidth of holograms was performed with success for angular, [8] wavelength, [9] [10] space-division, [11] polarization, [12] and sideband [13] [14] multiplexing schemes. Digital holograms can be numerically multiplexed and demultiplexed for efficient storage and transmission.
Theories of holographic consciousness have also been proposed as a potential explanation for capabilities such as the brain's capacity to retain memories despite extensive damage, [9] the human ability to rapidly discern and integrate large amounts of related data, [10] and a number of documented phenomena which indicate non-locality as a ...
