  2. Holography - Wikipedia

    en.wikipedia.org/wiki/Holography

    Holography. 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 .

  3. Holographic principle - Wikipedia

    en.wikipedia.org/wiki/Holographic_principle

    Holographic principle. The holographic principle is a property of string theories and a supposed property of quantum gravity that states that the description of a volume of space can be thought of as encoded on a lower-dimensional boundary to the region — such as a light-like boundary like a gravitational horizon. [ 1][ 2] First proposed by ...

  4. Pepper's ghost - Wikipedia

    en.wikipedia.org/wiki/Pepper's_ghost

    "Holographic" show. An illusion based on Pepper's ghost involving projected images has been featured at music concerts (often erroneously marketed as "holographic"). [6] At the 2006 Grammy Awards, the Pepper's ghost technique was used to project Madonna with the virtual members of the band Gorillaz onto the stage in a "live" performance.

    This figure from the paper shows the lensing and holographic setup as well as several examples of shapes printed using the technique. The advantages are plenty: you could, for instance, produce ...

  6. Lenticular printing - Wikipedia

    en.wikipedia.org/wiki/Lenticular_printing

    Lenticular printing is a technology in which lenticular lenses (a technology also used for 3D displays) are used to produce printed images with an illusion of depth, or the ability to change or move as they are viewed from different angles. Examples include flip and animation effects such as winking eyes, and modern advertising graphics whose ...

  7. Computer-generated holography - Wikipedia

    en.wikipedia.org/wiki/Computer-generated_holography

    Computer-generated holography. 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. [ 1]

  8. Looking Glass says it can turn any photo into a hologram

    www.engadget.com/looking-glass-factory...

    It will normally cost $20 to convert 100 photos to holograms, but those who’ve backed the frame (starting with a $249 pledge) will get their first 20 conversions for free if the campaign reaches ...

  9. Volumetric printing - Wikipedia

    en.wikipedia.org/wiki/Volumetric_printing

    Volumetric printing is a three-dimensional digital-to-physical imaging technology developed in 2013 that uses ink or other pigments suspended in a volume to form a full-color volumetric scene in physical space. It is a static version of volumetric display. Volumetric prints are auto-stereoscopic, full parallax (in both horizontal and vertical ...
