A new type of holographic telepresence allows the projection of a 3D moving image without the need for 3D glasses or other auxiliary devices.

Science fiction is now close to become reality thanks to scientists at the University of Arizona College of Optical Sciences, which announced advances in hologram technology used to present 3D images. The team, led by Nasser Peyghambarian, has managed to reduce the time it takes to refresh 3D projections onto a novel photorefractive material.

“It is no longer something that is science fiction, it is actually something that you can do today,” Nasser Peyghambarian said. We have demonstrated the concept and it works”. Peyghambarian also said: “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.”

The “holographic telepresence” is limited to images 43 centimetres high and and the holograms’ movements are halting as it takes two seconds for them to “refresh.” The technology combines motion with an impression of genuine solidity.

Professor Nasser Peyghambarian said that it would take about seven to ten years’ work before a consumer version of the system was ready to test in people’s homes
