Nature study describes metasurface waveguide prototype for augmented-reality glasses
A Nature study reported an augmented-reality glasses prototype using a dual-layer metasurface waveguide with a 30-degree field of view.
The researchers said their prototype used interwoven metasurfaces to direct light in a thin waveguide while maintaining an 8-by-8-millimeter eyebox.
The paper reported that the prototype produced stable virtual images under outdoor ambient illumination; it is a research prototype, not a commercial product announcement.
