Professor Nasser Peyghambarian of the University of Arizona's College of Optical Sciences has revealed he and his research team have been able to "realize science fiction in the laboratory" by producing 3D holographic images similar to those seen in the original Star Wars . The system, which requires no glasses -- but, unlike the Princess Leia scene in Star Wars , does require a screen -- could eventually revolutionize motion pictures by displaying life-size holographic images that could be transmitted in real time into theaters -- allowing, for Example, live stage shows to be mounted in one city and watched in hundreds of other theaters with such realism that the actors would appear to be performing on the stage of each of them. In a description of his research published in the current Nature magazine, Peyghambarian indicated that the holographic display is currently in a relatively primitive stage (it can only update images every two seconds, so that they appear jerky); however, he said, it "brings us a step closer to the ultimate goal of realistic holographic telepresence with high resolution, full color, human-sized, 3D images that can be sent at video refresh rates from one part of the world to another."
