What is the holographic display?
The
holographic display is a type of three -dimensional display, but unlike three -dimensional effects achieved by traditional three -dimensional technologies, it includes a real parallax element. This means that the viewer can move around the picture in any direction and keep the picture integrity. This technology can be used in two ways. It can be used to create a holographic image on a flat surface that does not actually exist in three dimensions, but it seems that without any special glasses or other observation aids. The second application is to create a virtual image in space, which actually takes three dimensions and can be displayed from any direction, as if it were a real physical object.
Flat holographic display technology is not new and has been used for decades to create three -dimensional images on flat surfaces. Like all holographic displays, such a picture does not require any special glasses or other special equipment. Looks likeThe viewer's perspective, a three -dimensional image that seems to be turning in space. The most advanced versions of these displays are able to display three -dimensional versions of air maps that are commonly found on the Internet. When laying on the surface and lighting, objects and buildings seem to have a real substance and the viewer can move around the perimeter of the image. Objects and images maintain their perspective regardless of angle or tracking direction.
New technological advances have allowed a real three -dimensional holographic display. This technology uses special rotating mirrors and laser projectors to create an image that takes up space in three dimensions, but has no physical substance. The browser of such a display can move around the object in any direction and the object will maintain its integrity exactly as a real object. For example, holographic apple display can be perceived in exactly the same way asReal apple on the pedestal. Changing the perspective of observation in any direction will visually lead to the perception of the image in exactly the same way as it was a real object.
Research continues in both versions of this technology. In 2011, scientists from the Massachusetts Institute of Technology (MIT) also developed an early prototype for three -dimensional holographic television display. This would include existing television technologies that would allow three -dimensional television that shows the real image integrity and requires no special glasses. As the viewer changes its location with respect to the screen, it seems that the holographic display retains its shape and depth, unlike the current three -dimensional television images, which quickly distort and lose its ability to accurately depict three dimensions when the viewer's perspective moves for a critical angle.
