The movie “Star Wars” wowed audiences with its use of holograms -- 3-D impressions that were projected into thin air so that a person’s animated image seemed to materialize from nowhere.
For years such innovation was only the stuff of dreams. Now, scientists at the Institute of Creative Technologies in Los Angeles have conceived an invention that rivals Hollywood: a
3-D teleconferencing system that scans and then reflects images using a high-speed video projector. This amazing device operates at thousands of frames per second to display a 3-D headshot in real time. Phone calls may never be the same.
