Spatial Imaging Group
No longer active as of Spring 2004, the Spatial Imaging Group at the MIT Media Lab developed new technology and interfaces for high-quality 3D displays. The lab's research included: designing new hologram formats and optical printers; electro-holographic displays and methods for computing holograms; spatial interaction and information design; rapid rendering for spatial displays; and viewer-tracked autostereoscopic Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer.

MIT Media Lab
The MIT Media Lab is a research laboratory at the Massachusetts Institute of Technology, growing out of MIT's Architecture Machine Group in the School of Architecture. Its research does not restrict to fixed academic disciplines, but draws from technology, media, science, art, and design. , Media Lab's research groups include neurobiology, biologically inspired fabrication, socially engaging robots, emotive computing, bionics, and hyperinstruments. The Media Lab was founded in 1985 by Nicholas Negroponte and former MIT President Jerome Wiesner, and is housed in the Wiesner Building (designed by I. M. Pei), also known as Building E15. The Lab has been written about in the popular press since 1988, when Stewart Brand published ''The Media Lab: Inventing the Future at M.I.T.'', and its work was a regular feature of technology journals in the 1990s. In 2009, it expanded into a second building. The Media Lab came under scrutiny in 2019 due to its acceptance of donations ...

3D Display
A 3D display is a display device capable of conveying depth to the viewer. Many 3D displays are stereoscopic displays, which produce a basic 3D effect by means of stereopsis, but can cause eye strain and visual fatigue. Newer 3D displays such as holographic and light field displays produce a more realistic 3D effect by combining stereopsis and accurate focal length for the displayed content. Newer 3D displays in this manner cause less visual fatigue than classical stereoscopic displays. As of 2021, the most common type of 3D display is a stereoscopic display, which is the type of display used in almost all virtual reality equipment. 3D displays can be near-eye displays like in VR headsets, or they can be in a device further away from the eyes like a 3D-enabled mobile device or 3D movie theater. The term “3D display” can also be used to refer to a volumetric display which may generate content that can be viewed from all angles. One company that produces volumetric dis ...

Hologram
Holography is a technique that enables a wavefront to be recorded and later re-constructed. Holography is best known as a method of generating real three-dimensional images, but it also has a wide range of other Holography#Applications, applications. In principle, it is possible to make a hologram for any type of Holography#Non-optical holography, wave. A hologram is made by superimposing a second wavefront (normally called the reference beam) on the wavefront of interest, thereby generating an interference pattern which is recorded on a physical medium. When only the second wavefront illuminates the interference pattern, it is diffracted to recreate the original wavefront. Holograms can also be Computer-generated holography, computer-generated by modelling the two wavefronts and adding them together digitally. The resulting digital image is then printed onto a suitable mask or film and illuminated by a suitable source to reconstruct the wavefront of interest. Overview and ...

Optical Printers
An optical printer is a device consisting of one or more film projectors mechanically linked to a movie camera. It allows filmmakers to re-photograph one or more strips of film. The optical printer is used for making special effects for motion pictures, or for copying and restoring film material. Common optical effects include fade outs and fade ins, dissolves, slow motion, fast motion, and matte work. More complicated work can involve dozens of elements, all combined into a single scene. History The first commercially available, although not mass produced, optical printer appeared in 1927 and was called the Depue & Vance Daylight Optical Printer. It was mainly used to reduce standard prints to 16mm and allowed for operation without a darkroom except from loading the positive film magazine. In 1918, the cinematographer Carl Gregory came upon a printer made by G. J. Badgley of New York, designed to produce copies of a standard film using domestic size film stock. Realizing the p ...

Autostereoscopic
Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer. Because headgear is not required, it is also called "glasses-free 3D" or "glassesless 3D". There are two broad approaches currently used to accommodate motion parallax and wider viewing angles: eye-tracking, and multiple views so that the display does not need to sense where the viewer's eyes are located. Examples of autostereoscopic displays technology include lenticular lens, parallax barrier, and may include Integral imaging, but notably do not include volumetric display or holographic displays. Technology Many organizations have developed autostereoscopic 3D displays, ranging from experimental displays in university departments to commercial products, and using a range of different technologies. The method of creating autostereoscopic flat panel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
