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.
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.
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.
Holography is a technique for recording and reconstruction of wavefronts.. Holography and holographic may also refer to: . Holograph, a document written entirely in the handwriting of the person who signed it
Ordinary holograms are three-dimensional images encoded in a two-dimensional surface, such as the hologram on a typical credit card. "This time, the entire universe is encoded," he said.
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
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.
Holography is the science of producing holograms; it is an advanced form of photography that allows an image to be recorded in three dimensions. Subcategories This category has the following 4 subcategories, out of 4 total.
