Tokyo professor working on Invisibility Technology
Yahoo! News ^

Posted on 02/07/2003 2:12:46 PM PST by spetznaz

NEW YORK - A University of Tokyo professor claims he and his research team have developed a system that can make you 'invisible.'

Engineering Professor Susumu Tachi is in the early stages of technology that he says will eventually enable camouflaged objects to be virtually transparent by wearing an optical device.

Professor Tachi demonstrated the technology on Wednesday. In a photo of graduate student Kazutoshi Obana, it appears as if three men walking in the background can be seen 'through' Obana's green overcoat.

The retroreflective material of the coat acts as a screen and gives a transparent - or invisible - effect.

For the best effect - one that keeps the correct depth of focus - the observer needs to look through a pinhole.

Tachi's second example shows the image of the skeleton being projected onto a sheet of the retroreflective material, giving the impression the body has become transparent.

The technology could be useful in medicine, where surgeons might use it during operations to avoid having their fingers or surgical tools block their view.

In aviation, cockpit floors could become 'invisible' to assist pilots in landing.

Professor Tachi hopes to have a commercially viable system within a few years.

Is he 'The Invisible Man' by H.G. Wells? It looks like as if three men walking behind are seen through the body of graduate student Kazutoshi Obana during a demonstration of optical camouflage technology at the Tokyo University in Tokyo Wednesday, Feb. 5, 2003. The demonstration conducted by Faculty of Engineering Prof. Susumu Tachi is an early stage of his research that will eventually enable camouflaged objects virtually transparent by wearing an optical device. This photo was taken through a viewfinder that provides with a combined image of moving images taken behind Obana and him wearing a luminous jacket that makes a transparent effect. The technology can be useful for various professions such as surgeons who wish their own fingers and surgical tools won't block the view of affected parts and pilots who wish cockpit floors were transparent for landings

Interesting!

I wonder how long it will take before this technology is applied to the military. Actually come think of it i saw this article that was showing how military aircraft can be made 'invisible' to the human eye through the use of photochromatic tech (something similar to the Auston Martin Vanquish car in the latest James Bond flick).

So it appears invisible, because it is a screen, upon which a display of the background from another vantage point is projected.

Hardly true invisibility.

It will be interesting to see if this technology....if it is even real...can be expanded further.

I don't think its actually a screen. "retro-reflective" means the backward manipulation of the path of light. The suit could be somekind of fiberoptic material that bends light around the contours of the person wearing it.

The suit could be somekind of fiberoptic material that bends light around the contours of the person wearing it.

The description sounds more like a material that reflects the light from the back surface of fibers, rather than the front surfaces.

Tachi's second example shows the image of the skeleton being projected onto a sheet of the retroreflective material, giving the impression the body has become transparent.

This seems fairly clear it is a technology as I described. What you describe would likely have to be a near-solid mass, and inflexible (else it would conduct to the wrong place and angle).

So, no optical device worn = no "invisibility"

Wow. Big deal.

Didn't the Army test this sort of technology (making something invisible)? Seems I remember something that happened around WWII, that involved using Magnetic waves to make a Destroyer/Aircraft Carrier disapear. From what I understand the outcome of that experiment is still kind of hush, hush.

We are both wrong, I went to their research site. The image of the background was previously rendered on a computer and then projected in infared onto the object, in this case the coat, from a separate projector in front of the person. The infared light hits the special retroflective material and radiates visible light, albeit with much lesser intensity. Thats why the background image is only projected onto the person's suit. Not real invisibility, since the suit cannot emanate its own light nor can it take images of the background in realtime.

This "technology" appears to be just a reversal of the "blue screen" used for TV weathermen.

Now if we can only get the bad guys to wear these goggles we devised....

From Star Trek "Balance of Terror"

(Spock) "Invisibility is theoretically possible--the selective bending of light rays--but the power cost is enormous. They [the Romulans] may have found a way to solve that problem."

An interesting application of this technology would be to mount huge infared projectors unto reconisance or support aircraft. Digitally render the terrain of an urban combat zone. Load the renderings into the projectors, and then fly the planes over the warzone, with the projectors on. Then send in troops with the retro-reflective coats. To the enemy the troops would be nearly invisible.

The Philadelphia Expirement aka Project Rainbow. It was meant to create radar invisibility but has become the thing of conspiracy theorists. They made a movie about it "The Philadelphia Experiment"

This is a projection technology. For it to work the covering would have to "radiate" the background image. Different concepts are at work here.

I believe they never found it.

I recall reading about the military trying this once and a ship got projected elsewhere.

This stuff is more akin to teleportation though, not invisibility.

I dunno.

Why cant you see the bikerider through his arm? How come his head isnt invisible? It looks like the only thing it can make invisible is a single colored flat surface...which oh by the way...is great for projecting images onto...but I digress...alot of questions.
One thing is for sure...the writer of the article has to be the biggest dimwit reporter since Helen Thomas put pen to paper...or should I say chisel to stone tablet.

I would venture a guess that the military applications would probably be impacted quite a bit more than pilots trying to land a plane.

The thing that pisses me off is that I came up with this about 4 years ago, and even drew up plans for it. I couldn't figure out how to make it overall camo without it being pixelated, or complete camo on one side only. I didn't see any real defense use for it, because it would be too klunky or easily damaged for field deployment, and wouldn't be worth the cost of trying to affix it to aircraft. Especially when it's optical only, and not going to help with the heat or radar signature. Plus, I though the theory was so obvious that somebody had probably already played with it and rejected it. Cameras view the picture behind you, and then distribute it to banks of red/green/blue LEDs covering the other side, forming a mosaic of the image.

"Cameras view the picture behind you, and then distribute it to banks of red/green/blue LEDs covering the other side, forming a mosaic of the image."

The only problem is that the image would have to "know" from what angle the viewer will be looking - For two observers, one five feet to the left of center and one five feet to the right, the same pixel would have to be from a different image.

This is all BS. They have a camera in back and a poor projector in the front shooting the rear on the front in a very limited fashion.

Ancient technology, stinks. Godzilla was more modern than this in 1956.

I would also add that the 1956 Godzilla was better than the new Godzilla, although I still have trouble with the original in one aspect. How did that scientist think that showing a girl how he could kill tropical fish and turn them into skeletons would impress her?

Back to topic. I read an article in the Austin-American Statesman about 10 years ago about a high school student in Round Rock who had the idea of making cars invisible by using a series of cameras on one side with mirrors and a projection screen on the other. Also, George Lucas used a takeoff on this in the original Star Wars, by putting mirrors on the bottom of Luke Skywalkers car so it would reflect the surrounding ground and hide the tires. So, you're right, this is way old from a conceptual perspective.

I agree with everything you said and would add that what made the old Godzilla better than the new stuff was black & white film. It hides tacky things and adds a feeling of mystery to a picture IMO!
Any of the old black and white horror flicks are at least mostly watchable still.

Same principle as used in The Predator. Ideally, you would have to have every surface reflect the image directly behind the "invisible" object. As shown in The Predator, it was a series of interlocking flat planes of view.

Naval Historical Center FAQ on this nonsense (excerpt):

The "Philadelphia Experiment"

Related resources::

Office of Naval Research (ONR) fact sheet
UFO Research Guide
Photograph of USS Eldridge

Allegedly, in the fall of 1943 a U.S. Navy destroyer was made invisible and teleported from Philadelphia, Pennsylvania, to Norfolk, Virginia, in an incident known as the Philadelphia Experiment. Records in the Operational Archives Branch of the Naval Historical Center have been repeatedly searched, but no documents have been located which confirm the event, or any interest by the Navy in attempting such an achievement.

The ship involved in the experiment was supposedly the USS Eldridge. Operational Archives has reviewed the deck log and war diary from Eldridge's commissioning on 27 August 1943 at the New York Navy Yard through December 1943. The following description of Eldridge's activities are summarized from the ship's war diary. After commissioning, Eldridge remained in New York and in the Long Island Sound until 16 September when it sailed to Bermuda. From 18 September, the ship was in the vicinity of Bermuda undergoing training and sea trials until 15 October when Eldridge left in a convoy for New York where the convoy entered on 18 October. Eldridge remained in New York harbor until 1 November when it was part of the escort for Convoy UGS-23 (New York Section). On 2 November the convoy entered Naval Operating Base, Norfolk. On 3 November, Eldridge and Convoy UGS-23 left for Casablanca where it arrived on 22 November. On 29 November, Eldridge left as one of escorts for Convoy GUS-22 and arrived with the convoy on 17 December at New York harbor. Eldridge remained in New York on availability training and in Block Island Sound until 31 December when it steamed to Norfolk with four other ships. During this time frame, Eldridge was never in Philadelphia.

Eldridge's complete World War II action report and war diary coverage, including the remarks section of the 1943 deck log, is available on microfilm, NRS-1978-26. The cost of a duplicate film is indicated on the fee schedule. To order a duplicate film, please complete the duplication order form and send a check or money order for the correct amount as indicated on the NHC fee schedule, made payable to the Department of the Navy, to the Operational Archives, at the above address.

Supposedly, the crew of the civilian merchant ship SS Andrew Furuseth observed the arrival via teleportation of the Eldridge into the Norfolk area. Andrew Furuseth's movement report cards are in the Tenth Fleet records in the custody of the Modern Military Branch, National Archives and Records Admnistration, (8601 Adelphi Road, College Park, MD 20740-6001), which also has custody of the action reports, war diaries and deck logs of all World War II Navy ships, including Eldridge. The movement report cards list the merchant ship's ports of call, the dates of the visit, and convoy designation, if any. The movement report card shows that Andrew Furuseth left Norfolk with Convoy UGS-15 on 16 August 1943 and arrived at Casablanca on 2 September. The ship left Casablanca on 19 September and arrived off Cape Henry on 4 October. Andrew Furuseth left Norfolk with Convoy UGS-22 on 25 October and arrived at Oran on 12 November. The ship remained in the Mediterranean until it returned with Convoy GUS-25 to Hampton Roads on 17 January 1944. The Archives has a letter from Lieutenant Junior Grade William S. Dodge, USNR, (Ret.), the Master of Andrew Furuseth in 1943, categorically denying that he or his crew observed any unusual event while in Norfolk. Eldridge and Andrew Furuseth were not even in Norfolk at the same time.

Yea, well, they could not verify the outcome. They lost the ship.

USS Eldridge, a 1240-ton Cannon class destroyer escort built at Newark, New Jersey, was commissioned in August 1943. She was employed on escort duties in the Atlantic until May 1945, when she departed for service in the Pacific. Eldridge was decommissioned in July 1946 and placed in the Reserve Fleet. In January 1951, she was transferred to the Greek Navy, in which she served as Leon into the 1990s.

Source (same site as above) includes a picture of the ship at the tranfer ceremony.

Of COURSE it does!!!


1. Just look at the poor vanishing point in the perspective of the lines...
2. Look how SMALL the people are on the 'coat'...
3. Notice that the SHADOWS of the two do NOT appear at the LEFT of the 'coat' on the pavement.

Fake, Scam, BS... you name it: this photo is ALL of them!!!

It's not "fake". This coat demo was also shown on Fox News. What the article sort of glosses over, however, is that the guy is standing in front of a video projector which is projecting the scene taken by a TV camera on a tripod behind him. The special thing the coat does is to glow enough to make the projected mage plainly visible in daylight. Otherwise, a white cotton coat could be used.
