Breakthrough in Holographic Displays
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."
This could be used to simulate breasts and vaginas for lesbian sex simulations.

Hope they got the rest of it right.

I can hardly wait for this to be adopted! Though it seems that it needs some new drivers or something; 1/300 or so FPS isn't going to be nearly good enough to play TF2 on.

Judging by the article illustration its primary use will be to create Hollywood-style zombies.

From R(ing)TFA, it appears that this thin material allows taking of a holographic IMAGE quickly. It still would be incredible useful, as holographs can be viewed from multiple angles and are in 3 dimensions. A photograph that sticks out. Granted, most of the ones I have seen are pretty bad but in principle they could be useful. The medical application does sound handy : instead of flat 2d xrays, xray machines would be basically digital CT scanners that gather enough information to produce a 3d image from a specific angle. This digitally processed 3d model would then be used as the basis for forming a holograph, suitable for placement on the X-ray reading boards and having on a clip next to a surgeon during surgery.
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.
We are now closer to the era of holographic videos.
Of course the movies will be silent and the polymer records will have to spin at 78 million RPMs.
you can take it on the go with the help of the mobile emitter.
Did I just make a Voyager reference? Sigh...
Ars has better coverage which talks more about the polymers used and how this is actually achieved. It also has a link to the paper published in Nature (although you can only get an abstract if you're like me and don't have a subscription).
:-)
I submitted this story, too. So knowing Slashdot, we might see a dupe
Pharmaceutical data, my ass. We're looking at "Playboy 3D" material here, and a reason to go back to print media for everyone's monkey-stroking needs!
blow your mind already
one can only hope. let yOUR conscience be yOUR guide. you can be more helpful than you might have imagined. there are still some choices. if they do not suit you, consider the likely results of continuing to follow the corepirate nazi hypenosys story LIEn, whereas anything of relevance is replaced almost instantly with pr ?firm? scriptdead mindphuking propaganda or 'celebrity' trivia 'foam'. meanwhile; don't forget to get a little more oxygen on yOUR brain, & look up in the sky from time to time, starting early in the day. there's lots going on up there.

is it time to get real yet? A LOT of energy is being squandered in attempts to keep US in the dark. in the end (give or take a few 1000 years), the creators will prevail (world without end, etc...), as it has always been. the process of gaining yOUR release from the current hostage situation may not be what you might think it is. butt of course, most of US don't know, or care what a precarious/fatal situation we're in. for example; the insidious attempts by the felonious corepirate nazi execrable to block the suns' light, interfering with a requirement (sunlight) for us to stay healthy/alive. it's likely not good for yOUR health/memories 'else they'd be bragging about it? we're intending for the whoreabully deceptive (they'll do ANYTHING for a bit more monIE/power) felons to give up/fail even further, in attempting to control the 'weather', as well as a # of other things/events.

dictator style micro management has never worked (for very long). it's an illness. tie that with life0cidal aggression & softwar gangster style bullying, & what do we have? a greed/fear/ego based recipe for disaster. meanwhile, you can help to stop the bleeding (loss of life & limb);
http://www.cnn.com/2007/POLITICS/12/28/vermont.banning.bush.ap/index.html
the bleeding must be stopped before any healing can begin. jailing a couple of corepirate nazi hired goons would send a clear message to the rest of the world from US. any truthful look at the 'scorecard' would reveal that we are a society in decline/deep doo-doo, despite all of the scriptdead pr ?firm? generated drum beating & flag waving propaganda that we are constantly bombarded with. is it time to get real yet? please consider carefully ALL of yOUR other 'options'. the creators will prevail. as it has always been.
corepirate nazi execrable costs outweigh benefits

as there are no benefits, just more&more death/debt & disruption. fortunately there's an 'army' of light bringers, coming yOUR way. the little ones/innocents must/will be protected. after the big flash, ALL of yOUR imaginary 'borders' may blur a bit? for each of the creators' innocents harmed in any way, there is a debt that must/will be repaid by you/us, as the perpetrators/minions of unprecedented evile, will not be available. 'vote' with (what's left in) yOUR wallet, & by your behaviors. help bring an end to unprecedented evile's manifestation through yOUR owned felonious corepirate nazi glowbull warmongering execrable. some
Why does every always assume that new technology could be applied to humanitarian applications? I think we need holographic images of stuff getting blowed up!
BBC's coverage is pretty lame. Slashdot would serve its readers better by linking to coverage at a science blog instead. For instance, Ars Technica's Nobel Intent science journal has a far superior writeup of the announcement.
The BBC writeup isn't very good. Try Ars Technica's coverage and you'll see that it's a 100 cm^2, rewritable holographic display. Or you can read the scientific paper in Nature.
:-)
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

:D?
Is anyone else getting these tags?
I caught the helpmeobiwan reply (pretty funny btw) but what has Yahtzee got to do with this
Great! Now I can print all of my Hannah Montana concert pics in 3D!
Los Angeles - Vivid Entertainment Group announced on Wednesday that it has just signed a contract with Savas Tay and colleagues at the University of Arizona to license their 3D technology for an upcoming "adult extravaganza" starring Jenna Jameson, Sunny Leone, and Tera Patrick.
Careful What You Wish For....
BBC's news coverage is fine, dickhead. It's a news site, not a science blog. Has more readers than /., for one thing. A few US news organisations could do with being as impartial and as comprehensive.
PS. Mod this one "Flamebait". Hope this helps.
So this seems like its moving toward a holograph writer which you could install in your PC. Then you could write holograms just like you burn a CD, but would these holograms have more or less storage capacity than what we have now?
In minutes? Wake me up when holographic images can be created in tens of milliseconds. Also, I demand a 20 cubic foot recessed tabletop display. Finally, it probably needs to cost under $500, so we can put one in every classroom.
OK, back to sleep now.
Shop as usual. And avoid panic buying.
I'm not exactly an expert in polymer science, nor in holography, so forgive me if this is ridiculous, but would it be possible to do some kind of layering so that, supposing a full read-write cycle took 5 minutes, you could layer 60 sheets to get 12 fps? I know there was an article a month or two ago about some Israeli company designing a 100-layer DVD, so I don't know how far fetched that is, and how different the lasers in holography are from optical drives. Just a thought.
The material has been shown to stay stable throughout hundreds of write and erase cycles.
Yeah, well what happens when you are on a starship and get hurt and need a doctor and you run out of polymer?? The devil's always in the details. First Hillarycare, now this!!

"Normally holographic images are created by mixing the results of multiple laser lights to lay down a static image, a lengthy and delicate process"
Wrong. Ive got the kit in front of me. Phase sensitive coated photgoraphic plate. Colliminated laser.
Set it up (dead simple. objetc+plate+point laser at it) and then develop it.
The hard part is stopping the damn vibrations and getting a clear imag.
will need to speed up their stuff
Lived in AZ for years, never heard of Tucson University lol.
I'm starting to get tired of seeing the "vaporware" tag for stuff that actually exists. Just because you can't buy it yet doesn't mean it's vaporware. Now had the scientists said, "We came up with an idea that would allow us to make a material that will/might/should display a hologram/holograph in minutes", and it's touted as something that will be available, then it's vaporware.
However:
"The material has been shown to stay stable throughout hundreds of write and erase cycles."
and
"The team has automated the process of capturing, writing and erasing images via a system that can take input from MRI, CAT scans, satellite or aerial photographs and microscopes."
Shows that it not only exists (and will probably blend), but they've already tested methods of putting it to practical use. Notice how these statements are "past-tense"?
Now, git off ma' lawn!
You decide.
