Immersive Digital Experiences Alliance (IDEA) Pushes Light Field Display Technology
Coined by physicist Andrey Gershun in 1936, a “light field” can be defined as a vector function that “totals all light rays in 3D [three-dimensional] space, flowing through every point and in every direction.” A light-field display (LFD) is what would reproduce a window-like, 3D aerial image, without the need for glasses or headwear—allowing the consumer to view the visual representation from any perspective. The idea itself dates back over a century ago to the concept of Integral Photography by Gabriel Lippmann. A user can get closer to the window or move far to one side and see different information, just like real life. If the user is very close to the window they can be completely immersed in this other reality. When they reach the edge of the window they won’t see any more content. And the creator of a light field gets to decide how large or small that window is, based on their specific uses. A light field volume creates images taken from every viewable position within a defined space. When the head moves, the correct images are swapped in real time.
