Researchers develop interwoven metasurface waveguide AR glasses prototype

Researchers have developed an all-day-wearable augmented reality glass prototype utilizing spatially varying, interwoven metasurfaces that provide multidirectional light control. The dual-layer metasurface-based waveguide achieves a 30-degree field of view, an 8 by 8-millimeter two-dimensional eyebox, and a high luminance efficiency within a 1.5-millimeter-thick form factor. This design demonstrates stable virtual image production under outdoor ambient illumination, bringing high-performance augmented reality glasses closer to consumer applications. Open article →
