Volfoni's 3D Elliptical Polarization Gets US Patent
Volfoni has been granted patent number 10,151,932 in the U.S. territory for its three dimensional elliptical polarization. Previous third-party cinema systems for 3D have required the use of passive 3D glasses based on either circular or linear polarization. Volfoni’s innovation instead uses passive 3D glasses based on elliptical polarization. According to the company, this not only improves the overall light efficiency and performance, but also avoids a host of other third-party choices, which specifically mandate the use of circular polarization.
