A team of geeks at the University of Utah is telling the Deseret News that it has come up with a better way to make those holograms you see displayed on packaging and seals. However, they do say that the technology could be applied to live hologram displays as well in VR headsets, movies, and moving 3D video in possibly as few as two years. Bet those guys in Utah have not thought of just how big this will be in the pr0n industry...yet. Surely the Pre-Crime Unit will show up when that happens though.
Menon and his team discovered a way that borrows from the same principle behind how wings of certain butterflies display their colors. Instead of reflecting only the colors you see while absorbing the rest, all of the white light is redirected so you see the wavelengths of the wing’s colors at different locations. None of the light is absorbed and wasted, he noted.
"Projecting an image before was very inefficient, and you need a massive lamp," Menon said. "Here, you can just do it with just a piece of plastic and a flashlight. It’s much simpler and more efficient this way."
He said the technology could be used on currency notes with security holograms that produce more life-like images. Currently, holograms on some foreign currency or on credit cards look like shimmering monochromatic images, he explained, but the new holograms would resemble full-color photographs.
The technology could also be used for identification badges, drivers’ licenses and security documents like passports, Menon noted. Typically, an officer could simply use a flashlight to authenticate security documents or badges with the new technology rather than an infrared scanner as is now required.
