Abstract

A cloaking device includes an object-side, an image-side, a cloaked region (CR) between the object-side and the image-side. An object-side CR reflection boundary, an object-side half-mirror, and an object-side multiband dichroic color filter are positioned on the object side and an image-side CR reflection boundary, an image-side half-mirror, and an image-side multiband dichroic color filter are positioned on the image-side. The object-side half-mirror and the object-side multiband dichroic color filter are spaced apart from and positioned generally parallel to the object-side CR reflection boundary, and the image-side half-mirror and the image-side multiband dichroic color filter are spaced apart from and positioned generally parallel to the image-side CR reflection boundary. Light from an object located on the object-side of the cloaking device and obscured by the CR propagates via three optical paths to form an image of the object on the image-side of the cloaking device.
