Abstract

A team of MIT scientists has developed a prototype for a small, inexpensive, holographic video system that works with consumer computer hardware such as PCs or gaming consoles, thereby enabling users to view images in three dimensions. The Mark III display could enhance participation in video games and virtual worlds, which currently are displayed mainly in two dimensions. The technology could also let doctors better view medical images such as those produced by magnetic resonance imaging. It could also help designers of complex objects such as cars. To create a holographic video, the Mark III´s software produces a 3D model of objects within a scene. The software then calculates how the device must process laser beams to create a 3D hologram that looks like the model from all viewing angles. Holograms result from a diffraction pattern that occurs when light waves interfere with one another after passing through a modulator. Mark III holographic
