AR Glasses with Single Micro-display and Optics Based on Polarization Volume Hologram (PVH)

A new compact AR/VR display glasses with single imager combined with optics based on multiple polarization volume hologram (PVH) of flat phase elements [1] as ultrathin surface lens integrated with a transparent flat plastic lens to reduce cost, weight, and volume is proposed. With specific optical characteristics of design and method of the PVH to diffract light beams at predefined via total internal reflection (TIR) emulating conventional freeform technique in the embodiment is described and simulated to achieve high optical efficiency at 50% up to 100% (if double layers of PVH used) of glasses light engine. It is significantly shifting the paradigm of the present AR or VR optical designs potentially benefiting the general consumers.
