Inspired perhaps by Harry Potter's invisibility cloak, scientists have recently developed several ways—some simple and some involving new technologies—to hide objects from view. The latest effort, developed at the University of Rochester, not only overcomes some of the limitations of previous devices, ...
{"Image ImageDescription": "A multidirectional `perfect paraxial' cloak using 4 lenses. For a continuous range of viewing angles, the hand remains cloaked, and the grids seen through the device match the background on the wall (about 2 m away), in color, spacing, shifts, and magnification. The edges of the optics can be seen since this is a small-angle ('paraxial') cloak, but this can be reduced by using large optics and for distant viewing; also the center of the device must not be blocked. // an optical cloaking configuration designed by University of Rochester professor of physics John C.
