University of Arizona scientists have developed a holographic telepresence system that projects a 3D, full-color, moving image -- but doesn't require viewers to wear special glasses to see the image properly.

"Let's say I want to give a presentation in New York. All I need is an array of cameras in my Tucson office and a fast Internet connection. At the other end, in New York, there would be a 3D display using our laser system," said optical sciences professor Nasser Peyghambarian in a statement.

A prototype of the holographic technology records an image with an array of regular video cameras, each one viewing the object from a different angle. Then it uses fast-pulsed laser beams to create holographic, or 3D, pixels. Those pixels are the building blocks of the images, according to the university.
