CAMBRIDGE, Mass. — Researchers have produced a three-dimensional image that appeared to be floating in space to demonstrate creation of the first free-standing hologram.
Using lasers, computers, a mirror, fiber optics and special film, the researchers generated a solid-looking image of a 9-by-4-inch green Chevrolet Camaro that seemed to be suspended in front of a darkened alcove.
"You can walk up and put your hand through it," said Tim Browne, assistant director of the Media Laboratory at Massachusetts Institute of Technology, which developed the technology. "It's amazing."
May Aid Surgeons
The researchers hope the new technology will eventually have wide applications--from allowing doctors to visualize surgery before entering the operating room to letting architects see their buildings without models.
