US Patent 11536976 Augmented reality display

An augmented reality display for displaying, in addition to a light field of a surrounding, an image to a user's eye, comprises a support, a light source to emit a collimated light beam carrying said image, a micro-electro-mechanical-system, MEMS, mirror to deflect the collimated emitted light beam as a collimated deflected light beam, a waveguide to guide and couple the collimated deflected light beam out as a collimated expanded light beam, and a semitransparent combiner to superpose the collimated expanded light beam as an image light beam with the light field of the surrounding for displaying to the user's eye.
