Cloaking System Could Make Blind Spots, Surgeons’ Hands Disappear
by Michael Keller
Scientists investigating the principles of how light behaves have developed a simple way to make objects disappear right before your eyes. It’s not magic; it’s optics.
University of Rochester researchers have used a set of lenses to manipulate focal lengths and create a region that is invisible when peering through the looking glass. They set up four lenses in a way that maintains cloaking in the region even when viewed from several degrees off of straight on.
The team says their system is the first to offer flexibility in viewing angles with a simple, inexpensive design.
