Breakthrough in Holographic Displays

ScuttleMonkey posted more than 6 years ago | from the deck-of-holos dept.

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."

ShooterNeo (555040) | more than 6 years ago | (#22326332)

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.

No, it's a display. (2, Informative)

Anonymous Coward | more than 6 years ago | (#22326918)

The BBC writeup isn't very good. Try Ars Technica's coverage [arstechnica.com] and you'll see that it's a 100 cm^2, rewritable holographic display. Or you can read the scientific paper in Nature [doi.org] .

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 :-)

I've seen some pretty high quality ones in a museum once, but it sounds like this one's quality is horrible. The article says, "almost as sharp as those broadcast on US television." I'm having a hard time thinking of a less sharp image that most people would be familiar with and it's not even that good.

> 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.

Reading the article, I was decidedly unimpressed at the thought that this would be useful for surgery. You see, there are already software applications that can take a stack of CT images and create a 3d "flythrough" view. This technology already exists for PCs, so having a holographic version of the same thing seems like a HUUUUGE step backward, and is not worth the money you'd have to spend on holographic film vs. a piece of software (which could even be included in the price of either the modality (CT, MRI, etc) or a PACS (Picture Archival And Communication System) which is already needed to store the digital images.

I work in a hospital's IT department and saw such a thing at the RSNA (Radiological Society of North America) conference in 2006. At the time, it was mostly smaller systems, such as a heart or blood vessels, but the idea is certainly able to be expanded to larger areas, if necessary. Of course, if it is for surgery, a much larger area would usually be unnecessary.

It only takes minutes if you're making it on the re-writeable photorefractive polymers, of which this new one is an improvement.

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"?
