Optical Waveguide
An optical waveguide is a display technology used in AR glasses that guides light to the human eye through total internal reflection. It offers advantages such as being thin and lightweight and suitable for outdoor use, but presents challenges including low optical efficiency.

Consumer-grade AR glasses mainly adopt the optical waveguide approach, in which images are emitted by a micro-projector or Micro-LED light source, coupled via a grating into the glass lens, guided to the front of the eye through multiple total internal reflections, and finally diffracted into the pupil by an output grating.
