Patent Applications by Meta Platforms Technologies, LLC
Abstract: a reflective polarization volume hologram (rpvh) layer in combination with a quarter wave plate (qwp) is used to provide optical power and to correct chromatic aberration in an optical assembly of an augmented and/or virtual reality (ar/vr) near-eye display device. the rpvh layer introduces more degrees of freedom to further improve contrast of the optical system and reduces a thickness/weight of the optical assembly. the rpvh layer is flexible, thus, allowing curved lamination on an optical lens. moreover, the rpvh layer is sensitive to circular polarization. thus, it can filter right-handed circular polarization (rhcp) or left-handed circular polarization (lhcp), without a need for the qwp.
