Abstract

A cloaking device includes cloaking region boundary planes oriented non-planar to each other, each of the cloaking region boundary planes having an outward facing mirror surface and an inward facing opaque surface. The cloaking device includes a cloaking region bounded at least partially by the inward facing opaque surfaces of the cloaking region boundary planes. Light from an object positioned on the object-side of the cloaking device and obscured by the CR has a first optical path through the cloaking device and light from the object not obscured by the CR has a second optical path through the cloaking device. A first matching medium is positioned between the object-side and the image-side in the second optical path and increases the second optical path length such that an optical path difference between the first optical path length and the second optical path length is reduced.
