A team at the University of Arizona 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 3-D glasses or other auxiliary devices.

"Holo" Victory

I'm Bob Karson with the discovery files -- new advances in science and engineering from the National Science Foundation.

(Sound effect: sound byte) "I saw the "Star Wars" movie, I don't know, 25-30 years ago. Princess Leia comes out of R2-D2 -- out of nowhere, right? That was science fiction. Now, we're pretty much there, we can actually do this."

Nasser Peyghambarian (pronounced: pay-gam bear-yan) of the University of Arizona, lead researcher on a team that's developed a new type of 3-D holographic imaging or "telepresence." It means that we can now record a three-dimensional, moving image in one location and show it in another location in real time -- all without the use of those freaky 3-D glasses.

Most of us have seen static holograms or 3-D images. The difference here is it's the first real time (or close to real time) moving hologram on a screen. You can look from left or right, top or bottom, and see the subject from a different angle. What the researchers call, "full parallax" -- for a very lifelike view.

The system uses an array of regular cameras and, with the help of laser beams, creates an image on a special photorefractive polymer screen. Add a high-speed internet connection and the image signals can be transmitted and projected anywhere in the world.

Practical uses of this technology could range from medicine to advertising.

Though primitive and monochromatic, the real-time, moving hologram is here. If you're an actor, soon every side will have to be your "good side."

"The Discovery Files" covers projects funded by the government's National Science Foundation. Federally sponsored research -- brought to you, by you! Learn more at nsf.gov or on our podcast.
