Paraxial cloak design and device

摘要

A paraxial cloaking device provides a cloaking volume in which an item can be hid from view. A cloaking device includes an optical input receiving light rays and an optical output from which a continuous range of directions of the received light rays exit the paraxial cloaking device. The cloaking volume being disposed between the optical input and the optical output. For received light rays having incoming directions non-parallel to the reference optical axis up to a first angle, each of the received light rays exits the cloaking device substantially aligned with the respective received light ray and does not pass through the cloaking volume. The paraxial cloaking device has a unity magnification factor. In some instances, the paraxial cloaking device includes a phase matching element.

1. A paraxial cloaking device having a cloaking volume and a reference optical axis, the device comprising:
an optical input receiving light rays; and an optical output from which a continuous range of directions of the received light rays exit the paraxial cloaking device, the optical output being offset from the optical input, the cloaking volume being disposed between the optical input and the optical output, wherein, for the received light rays having incoming directions non-parallel to the reference optical axis up to a first angle, each of the received light rays exits the cloaking device at the optical output substantially aligned with the respective received light ray and does not pass through the cloaking volume, wherein the paraxial cloaking device has a unity magnification factor and is afocal.
