  • Patent number: 10739111
    Abstract: Digital cloaking is a method for practical cloaking, where space, angle, spectrum and phase are discretized. At the sacrifice of spatial resolution, a good approximation to an ideal cloak can be achieved—a cloak that is omnidirectional, broadband, and operational for the visible spectrum, three-dimensional (3D), and phase-matching for the light field, among other attributes. One example of a digital cloak is an active cloak that uses lenticular lenses, similar to integral imaging for 3D displays. With the continuing improvement in commercial digital technology, the resolution limitations of a digital cloak may be minimized, and a wearable cloak can be implemented.

  • Patent number: 10685492
    Abstract: Designs useful for switchable “Virtual Reality,” “Augmented Reality,” and “Mixed Reality” (VR/AR/MR) devices, for combining real reality and simulated reality images, other display purposes, and more. Various methods are proposed to combine (or not) real reality with simulated reality through the use of some level of zooming, cloaking, and/or other techniques. This enables a switchable VR and AR/MR system that does not require transparent glasses or devices. Various systems and methods are presented, some that can be generalized to novel imaging and display techniques that have broad applications beyond VR, AR, MR and other fields.

  • Patent number: 9557547
    Abstract: 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.
