Getting the properties of invisibility is probably one of the most coveted sci-fi dreams: we have seen this property in spy feature films, video games, cartoons, read about it in art books. Although scientists from the University of Rochester has not yet been solved a puzzle that would create invisibility cloak, they were able to create a very interesting optical illusion.

Taking a few optical lenses and performing highly complex mathematical calculations, the team created an optical instrument capable of refracting light waves around small objects. When one looks through the system, located in front of her to really disappear. Put the device in front of your hand and you will not see part of it. In addition, it is the first three-dimensional system in which the background is still visible, while the item you want to hide, remains invisible.

Of course, the system is imperfect, and there are a number of limitations. For example, the illusion of invisibility will work only within the optical lens through which to view people. In the video below on the time of 2:00 – 2:07 you can see that a “hidden” object for a moment becomes visible.

And yet, although scientists have so far failed to create a real invisibility cloak, created an optical illusion really looks cool.
