High-Efficiency and Compact Two-Dimensional Exit P by adrianete13 is a document available to read on EtoBox.
This research article presents a novel two-dimensional exit pupil expansion (2D-EPE) design for a diffractive waveguide using polarization volume grating (PVG), aimed at enhancing augmented reality (AR) displays. The proposed design achieves a diagonal field of view of 30° with an exit pupil magnification of nearly 20 times and demonstrates improved optical efficiency and reduced light leakage compared to existing systems. Experimental results validate the feasibility of the PVG-waveguide technology, markin
