Breakthrough in Holographic Displays 59
bendodge writes to mention the BBC is reporting that researchers at the University of Tucson, Arizona have created a polymer that allows holographic images to be created in minutes. Normally holographic images are created by mixing the results of multiple laser lights to lay down a static image, a lengthy and delicate process. "In a paper in Nature Mr Tay and colleagues describe their thin-film polymer that can have images 'written' to it in minutes and can be wiped as quickly to take and display another image. The material has been shown to stay stable throughout hundreds of write and erase cycles. The ability to quickly refresh images in holographs could mean that surgeons use them as a guide during operations or as a better way for pharmaceutical researchers to study molecular interactions for new drugs during simulations."

Hope they got the rest of it right.

BUT...it is by no means a 3d display. The best way to have full motion, high resolution 3d images is still using a head mounted display combined with a sensor for tracking head movement.

I submitted this story, too. So knowing Slashdot, we might see a dupe

No, it's a display. (Score:2, Informative)
It really is a holographic display. It uses a mixture of two polymers and quite a few kilovolts to zap things into place, after which you get a nice little display. It takes about half a second to form the image, which then lasts for about 3 hours (compared to it vanishing in about as much time as it took to create the image before). The device is also a lot bigger than previous devices.
I covered all that in my submission, but I guess someone beat me to submitting the story. Oh well, I've got plenty of accepted submissions already, anyhow, and knowing Slashdot, they could use my submission for a dupe, tomorrow

If you're using plain old film to make a non-re-writeable hologram, then it takes about as long as it takes your film to expose.
