Scientists say they have taken a big step toward displaying live video in three dimensions -- a technology far beyond 3-D movies and more like the "Star Wars" scene where a ghostly Princess Leia image pleads, "Help me, Obi-Wan Kenobi."
"It is actually very, very close to reality. We have demonstrated the concept that it works. It's no longer something that is science fiction," said Nasser Peyghambarian of the University of Arizona.
Projecting holograms would require "a material that can store shifting holographic data moves the fantasy into the realms of reality. The substance could have future applications in medicine and manufacturing, as well as in the entertainment industry.... The challenge was to find a rewritable material that could store data encoding successive holographic images. Now Peyghambarian and his colleagues have developed a material that can record and display 3D images that refresh every two seconds."
Yes, I know "holodeck" is from a different series. =P
