Invisibility Cloak Is A Reality Now – Scientist Explains
Scientists at the University of Rochester have created an optical-illusion device they’re calling a sort of invisibility cloak.
It’s a stationary trick that bends light around smaller objects — rulers and pens are used as examples by these researchers — so that they seem to have disappeared. Four regular lenses are arranged like this:
If used correctly, you can see beyond the lenses but not what’s between them. Researchers have provided a video to show how it’s done. Physics professor John Howell and grad student Joseph Choi are calling it the first device with three-dimensional, multidirectional cloaking.
“There have been many high-tech approaches to try and achieve cloaking,” Howell said in a video. “We just figured a very simple way of doing that can just be using standard lenses and things that we would normally find in the lab.”
