The Rochester Cloak is the next step in developing an invisibility cloak. It uses ordinary lens to bend light around an object, making it appear invisible. In the past, limitations of “invisibility devices” were that you had to stay in one place for it to work. Move the slightest bit and you saw both the object and the invisibility device itself, which defeats the whole purpose. This device, however, does not have that problem.
Though it’s not yet ready for superhero excursions, it has the opportunity for more scientific uses, including surgeons seeing past their hands during an operation. Even better, this has the potential to be scalable, using bigger lens to cloak bigger objects.
