If you've been fantasizing about becoming a hologram (no, not like Jem) since you saw Princess Leia make a plea to Obi-Wan Kenobi in 'Star Wars,' your nerdiest dreams may soon become a reality. A team of researchers at the University of Arizona reported in the latest issue of the science journal, 'Nature,' that they're working on a holographic technology, which will display images in alternate locations -- updated in real-time.
The group from the university's College of Optical Sciences is pairing up with Nitto Denko Technical Corporation to create a 3-D telepresence in full-color (no glasses needed), which would be viewable from all sides. How does it work? In plain speak, a variety of perspective shots are captured on a series of cameras -- arranged in an arc or circle. The info is processed and sent via computer to another location -- essentially anywhere in the world. The 3-D holographic system "prints" the images onto a screen with a laser, which are updated every two seconds, and all that's needed to illuminate the image is light.
