Researchers Choi and Howell Create Digital Cloaking Device

Using the same mathematical framework as the Rochester Cloak, Dr. Joseph Choi of the Institute of Optics (left) and Prof. John Howell (lower right) of the Department of Physics and Astronomy have used flat screen displays to extend the range of angles that can be hidden from view. Their method lays out how cloaks of arbitrary shapes, that work from multiple viewpoints, may be practically realized in the near future using commercially available digital devices.

The Rochester researchers have shown a proof-of-concept demonstration for such a setup, which is still much lower resolution than the nearly perfect imaging achieved by the Rochester Cloak lenses. But with increasingly higher resolution displays becoming available, the “digital integral cloak” they describe in their new Optica paper will continue to improve.
