Scientists develop new invisibility cloak

A team at the University of Rochester has come up with a new way to hide 3-dimensional objects from view.
The method, which could give even Harry Potter's invisibility cloak a run for its money, uses a combination of readily available optic lenses to render an object undetectable.

Unlike previous invisibility cloak concepts that involve special materials or cameras that project the image behind on to the front of the cloak to conceal an object, this one uses nothing but four simple lenses to achieve the invisibility effect.
"From what, we know this is the first cloaking device that provides three-dimensional, continuously multidirectional cloaking," said graduate student Joseph Choi.

"I imagine this could be used to cloak a trailer on the back of a semi-truck so the driver can see directly behind him. It can be used for surgery, in the military, in interior design, art."

I can't see this happening...

new invisibility cloak? .. what happened to the old one? It became invisible... no-one could find it.

This is amazing. I want to know exactly how it works. The explanation is in either the article or the vid, I can't recall which. But, unlike the pic, it's NOT like a multi-lens magnifying glass that you can hold in one hand and see through a wall or something, Instead it is a multi-lens system separated from each other, and the "cloaked" object MUST be in-between one of the four lenses at a specific point(I think between the 1st and second lens...not sure) The vid shows this.

Now if this concept could be made practical on a large scale, would a stealth bomber with this technology lose it's radar protection? I don't see this particular system working on a plane, because it is based on lenses that are pretty far away from each other. Basically the lenses would have to be the size of a stealth bomber and be a hundred feet above and below the bomber. And the bomber would have to have a hole in the middle for the light to go from one lens to the other. And only those looking directly at the bottom lens toward the top lens would fail to see the bomber, the other 9999 ang... [More]

This device would be particularly cumbersome for large object cloaking, as all 4 lenses would have to be as large as the object desired to be cloaked. On a smaller scale it seems to works just fine as described. This is more like "basic science investigation" for "proof-of-concept" It's actual utility in the real world is highly limited at this time... perhaps for magicians or such. However, in all due regard, I fully respect both the invention itself and the progress that "basic science" makes. It would not be the first time that "basic science" discoveries have been tweaked to advanced level... [More]

I dont see any applications for airplanes, but for law enforcements or security? and maybe land forces like hide a missile postation or artillery or a advanced stealth position in enemy territory?

They didn't say, but I wonder if you looked through the thing from the other end, would it produce the same cloaking effect?

WUT? This is nothing new at all. And these smug wannabes act like they just discovered alien technology. Hell I used to do this trick with my telescope pieces when I was 11 yrs old (in the early 80s). I mean, seriously?

I wish that they would use this technology for art or something recreational. but we all know that its going to be used for war.
