Cloaking devices constructed from reflection boundaries, half-mirrors and multiband dichroic color filters and vehicles comprising the same

A cloaking device assembly comprising:

• an object-side, an image-side, a cloaked region (CR) between the object-side and the image-side, and a reference optical axis extending from the object-side to the image-side;
• a first object-side CR reflection boundary, a first object-side half-mirror, and a first object-side multiband dichroic color filter positioned on a first side of the reference optical axis, wherein the first object-side half-mirror and the first object-side multiband dichroic color filter are spaced apart from and positioned generally parallel to the first object-side CR reflection boundary;
• a second object-side CR reflection boundary, a second object-side half-mirror, and a second object-side multiband dichroic color filter positioned on a second side of the reference optical axis opposite the first side, wherein the second object-side half-mirror and the second object-side multiband dichroic color filter are spaced apart from and positioned generally parallel to the second object-side CR reflection boundary;
• a first image-side CR reflection boundary, a first image-side half-mirror, and a first image-side multiband dichroic color filter positioned on the first side of the reference optical axis, wherein the first image-side half-mirror and the first image-side multiband dichroic color filter are spaced apart from and positioned generally parallel to the first image-side CR reflection boundary;
• and
• a second image-side CR reflection boundary, a second image-side half-mirror, and a second image-side multiband dichroic color filter positioned on the second side of the reference optical axis opposite the first side, wherein the second image-side half-mirror and the second image-side multiband dichroic color filter are spaced apart from and positioned generally parallel to the second image-side CR reflection boundary;
• wherein light from an object located on the object-side of the cloaking device assembly and obscured by the CR is redirected around the CR via at least two optical paths on the first side of the reference optical axis and at least two optical paths on the second side of the reference optical axis to form an image of the object on the image-side of the cloaking device assembly such that the light from the object appears to pass through the CR.

A vehicle comprising:

• an A-pillar;
• and
• a cloaking device positioned on the A-pillar, the cloaking device comprising:
• an object-side, an image-side, a reference optical axis extending from the object-side to the image-side, and a cloaked region (CR) between the object-side and the image-side, wherein the A-pillar is positioned within the cloaked region, the object-side is positioned on an exterior of the vehicle and the image-side is positioned within an interior of the vehicle;
• an object-side CR reflection boundary, an object-side half-mirror, and an object-side multiband dichroic color filter positioned on the object-side, wherein 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
• an image-side CR reflection boundary, an image-side half-mirror, and an image-side multiband dichroic color filter, wherein 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;
• wherein light from an object located on the object-side of the cloaking device and obscured by the A-pillar is redirected around the A-pillar via at least two optical paths to form an image of the object on the image-side of the cloaking device such that the light from the object appears to pass through the A-pillar.
