Integral imaging
Integral imaging is an autostereoscopic or multiscopic 3D display, meaning that it displays a 3D image without the use of special glasses on the part of the viewer. It achieves this by placing an array of microlenses (similar to a lenticular lens) in front of the image, where each lens looks different depending on viewing angle. Thus rather than displaying a 2D image that looks the same from every direction, it reproduces a 4D light field, creating stereo images that exhibit parallax when the viewer moves.
The concept was proposed in 1908 by Gabriel Lippmann, and to date has found use largely in the related concept of lenticular printing of static images.
Integral video
Experiments with integral video are now being worked on. Japan's NHK broadcasting company has shown off demos featuring a prototype display viewable from virtually any angle.[1][2] Toshiba has also begun research into the technology.[3]
