Patent ID: 10444480

Abstract:
A cloaking device includes an object-side, an image-side, a cloaked region and eight prisms positioned around the cloaked region. Each of the prisms has a light entrance side, a light exit side, a vertex formed from the intersection of a plane defined by the light entrance side and a plane defined by the light exit side, and a vertex angle between the light entrance side and the light exit side. A pair of first object-side prisms with inward facing vertices and a pair of second object-side prisms with outward facing vertices are positioned on the object-side, and a pair of first image-side prisms with outward facing vertices and a pair of second image-side prisms with inward facing vertices are positioned on the image-side. The light entrance sides of the pair of second object-side prisms are parallel and spaced apart from the light exit sides of the pair of first object-side prisms.
