Color near-eye display with high exit-pupil uniformity based on optimized meta-grating

A diffractive waveguide based on surface relief grating is one of the most significant components for near-eye displays (NEDs). Here, we propose a colorful NED system using meta-grating as the coupler to achieve high exit-pupil brightness uniformity and color uniformity. The whole system has a light...

Description
Summary:A diffractive waveguide based on surface relief grating is one of the most significant components for near-eye displays (NEDs). Here, we propose a colorful NED system using meta-grating as the coupler to achieve high exit-pupil brightness uniformity and color uniformity. The whole system has a lightweight and compact configuration and allows for flexible integration with ordinary smart glass. Our work provides a feasible way to design a colorful and miniaturized NED.
