Abstract
Described herein are systems and methods to provide privacy protection and brightness enhancement in an interactive environment. A system may include one or more of a headset, one or more light sources, one or more optical elements, one or more physical processor, and/or other components. A light source may be configured to generate linearly polarized light rays polarized on a first polarization plane along an axis of propagation. A reflective polarizer of an optical element may be configured to transmit light rays polarized on a second polarization plane transverse to the first polarization plane. Light rays polarized along the first polarization plane may be reflected off the reflective polarizer. An absorptive polarizer of an optical element may transmit light rays polarized on the second polarization plane so that light rays polarized along the second polarization plane may be transmitted through both the absorptive polarizer and the reflective polarizer.
