  2. Computer-generated holography - Wikipedia

    en.wikipedia.org/wiki/Computer-generated_holography

    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.

  3. Holographic display - Wikipedia

    en.wikipedia.org/wiki/Holographic_display

    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.

  4. Holographic screen - Wikipedia

    en.wikipedia.org/wiki/Holographic_screen

    A holographic screen is a two-dimensional display technology that uses coated glass media for the projection surface of a video projector. "Holographic" refers not to a stereoscopic effect, but to the coating that bundles light using formed microlenses. The lens design and attributes match the holographic area.

  5. Holography - Wikipedia

    en.wikipedia.org/wiki/Holography

    Two photographs of a single hologram taken from different viewpoints. 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.

  6. Volumetric display - Wikipedia

    en.wikipedia.org/wiki/Volumetric_display

    Volumetric displays are one of several kinds of 3D displays. Other types are stereoscopes, view-sequential displays, [2] electro-holographic displays, [3] "two view" displays, [4] [5] and panoramagrams. Although first postulated in 1912, and a staple of science fiction, volumetric displays are not widely used in everyday life. There are ...

  7. Physics of optical holography - Wikipedia

    en.wikipedia.org/wiki/Physics_of_Optical_Holography

    Holographic self-portrait, exhibited at the National Polytechnic Museum, Sofia. 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.

  8. Holographic optical element - Wikipedia

    en.wikipedia.org/wiki/Holographic_optical_element

    Holographic optical element (HOE) is an optical component (mirror, lens, directional diffuser, etc.) that produces holographic images using principles of diffraction.HOE is most commonly used in transparent displays, 3D imaging, and certain scanning technologies.

  9. Specular holography - Wikipedia

    en.wikipedia.org/wiki/Specular_holography

    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.
