“Digital Integral Cloak”: New Invisibility Cloak Uses Flat Screen Displays
Added May 19, 2016 | Rate View top rated
A Rochester Cloak is a cloaking device that can be built using inexpensive, everyday materials. Developed by University of Rochester researchers, the device features four standard lenses that allows an object to appear invisible as the viewer moves several degrees away from the optimal viewing positions. Using the same mathematical framework as the Rochester Cloak, University of Rochester researchers have been able to use 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, their new “digital integral cloak” will continue to improve.
