LinkNotes: Holograms

Japan scientists create 3-D images you can touch

TOKYO (Reuters Life!) - Imagine a light switch or a book that appears only when you need it -- Japanese scientists are one step closer to making the stuff of sci-fi films into reality after creating a hologram that can also be felt.

"Up until now, holography has been for the eyes only, and if you'd try to touch it, your hand would go right through," Hiroyuki Shinoda, professor at Tokyo university and one of the developers of the technology, told Reuters.

"But now we have a technology that also adds the sensation of touch to holograms."

Touchable holograms could be used for a wide variety of things... everything from light switches to books with each appearing when needed, and then disappearing when not.

And holograms could replace the need for making new interfaces for technology, since they could be changed without having to make a new physical product.

3-D Holography Breakthrough: Rewritable Holograms

University of Arizona optical scientists have developed a method of "rewriting" holograms. The holographic displays – which are viewed without special eyewear – can be erased and rewritten in a matter of minutes. This makes them them ideal tools for medical, industrial and military applications and also for consumer electronics like mobile phones and computer games.

Rewritable Holograms Could Appear in Mobile Phones

Imagine having a mobile phone wallpaper which is not a flat image, but a full 3D-Hologram, which can then be updated by the user just as easily as they currently buy replacement wallpapers. That is the promise which could come from a breakthrough by University of Arizona optical scientists. Cellular News reports.

3-D Holography Breakthrough: Erase And Rewrite In Minutes

"This is a new type of device, nothing like the tiny hologram of a dove on your credit card," UA optical sciences professor Nasser Peyghambarian said. "The hologram on your credit card is printed permanently. You cannot erase the image and replace it with an entirely new three-dimensional picture."

"Holography has been around for decades, but holographic displays are really one of the first practical applications of the technique," UA optical scientist Savas Tay said.
