The iconic “Star Wars” scene where R2-D2 projects a 3-D image of Princess Leia could be a reality sooner rather than later.
Brigham Young University physicist Daniel Smalley has developed a new technology, dubbed “volumetric display,” aiming to move beyond holograms and create moving 3-D images that can be seen from any angle. The tech functions as a “high-speed Etch a Sketch,” as the latest “Nature” journal describes it, using lasers to project its image.
“This is doing something that a hologram can never do — giving you an all-round view, a Princess Leia-style display — because it’s not a hologram,” Miles Padgett, an optical physicist at the University of Glasgow, told “Nature.”

So far, the technology is only being used on small pictures, with Smalley’s team recreating an image of a butterfly and a moving spiral outline. The projections were only a few millimeters, but some scientists see it as a leap forward from the “standard” hologram tech, which is only 2-D and lacks depth. Another bonus for volumetric display — it looks the same no matter what angle you’re looking at it from.

“You can have a circle of people stand around it and each person would be able to see it from their own perspective. And that’s not possible with a hologram,” said Curtis Broadbent, of the University of Rochester, to the New York Post.
While researchers work on beaming more life-sized images, it looks like “Star Wars” fans won’t have to wait another 41 years for this tech to become a reality.
