A team led by the University of Arizona professor of Materials Science and Engineering Nasser Peyghambarian has developed a new type of holographic telepresence that allows the projection of a three-dimensional moving image without the need for special eyewear such as 3D glasses or other auxiliary devices.
“Holographic telepresence means we can record a three-dimensional image in one location and show it in another location, in real-time, anywhere in the world,” said Peyghambarian, who led the research effort.
“Holographic stereography has been capable of providing excellent resolution and depth reproduction on large-scale 3D static images,” the authors wrote, “but has been missing dynamic updating capability until now.”
The prototype device uses a 10-inch screen, but Peyghambarian’s group is already successfully testing a much larger version with a 17-inch screen. The image is recorded using an array of regular cameras, each of which views the object from a different perspective. The more cameras that are used, the more refined the final holographic presentation will appear.
