TORONTO -- Researchers at Brigham Young University (BYU) in Utah have figured out how to use lasers to create sci-fi-style holograms. The holograms closely resemble and are inspired by laser displays seen in science fiction, such as the holodeck and phasers in “Star Trek” and lightsabers in “Star Wars.” The holograms don't require a screen or computer graphics. "Most 3D displays require you to look at a screen, but our technology allows us to create images floating in space -- and they're physical," said lead researcher Dan Smalley in a video released by BYU. Smalley and his team detailed their findings in a paper published last month in Nature's Scientific Reports.
