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.
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.
Zebra Imaging was a company that developed 3D digital holographic images, hologram imagers and interactive 3D displays for government [1] and commercial uses. The company offers digital holograms that are autostereoscopic (no glasses or goggles required), full-parallax (viewing of the image from viewpoints above and below as well as from side to side) and in monochrome or full-color.
Euclideon Pty Ltd is an Australian computer software company known for a middleware 3D graphics engine, called Unlimited Detail.Euclideon is also the parent company and operator of Holoverse, a 'holographic entertainment centre' located on the Gold Coast, in Queensland, Australia.
The current implementation of Project Starline is a booth that the user sits in, facing a 65 in (170 cm) "light field display," [7] surrounded by depth sensors, cameras, and lights. [ 5 ] [ 12 ] Light field technology is a photography technique that captures the direction of light as well as its intensity and color to enable more effective 3D ...
SLMs are used extensively in holographic data storage setups to encode information into a laser beam similarly to the way a transparency does for an overhead projector. They can also be used as part of a holographic display technology. In the 1980s, large SLMs were placed on overhead projectors to project computer monitor contents to the 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.
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.
