Invisibility cloak could soon be a reality
If current research proves fruitful, Harry Potter might get his invisibility cloaks from the University of Rochester as the university has taken the screens off their recent development, an invisibility cloak.
The scientists at the university have found a way to hide objects from sight. Some inexpensive lenses are used to hide objects which are already available and the lenses hide objects from sight. These lenses use a technology that was inspired by J.K. Rowling’s novel Harry Potter series.
Cloaking hides objects from its surroundings which is also invisible to the eye while the rest of the objects in the surroundings remain the same. John Howell, a physics professor of the upstate New York school said, “A lot of people have worked on a lot of different aspects of optical cloaking for years”.
Currently, the cloak is named Rochester-cloak as it is developed by the University of Rochester and it is not a tangible material. The device itself looks like an optometrist’s equipment which seemingly makes objects placed behind it disappear. There are other types of cloaking methods used previously and all of them are complicated and expensive and also unable to hide the three dimensional aspect of objects when viewed from different angles.
Joseph Choi who helped the cloaking method at Rochester said, “From what, we know this is the first cloaking device that provides three-dimensional, continuously multidirectional cloaking”. Rochester University is known for its research in optometry. The cloaking device is demonstrated by cloaking a hand, a ruler and a face while the part behind it seems to have disappeared, the rest of the object remains in view.
Choi also said how the cloak can be put to practical use. “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.”
