ALEXANDRIA, Va., March 19 -- United States Patent no. 12,253,669, issued on March 18, was assigned to GOOGLE LLC (Mountain View, Calif.).
"Time-sequential MEMS projector" was invented by Daniel Adema (Kitchener, Canada).
According to the abstract* released by the U.S. Patent & Trademark Office: "A display system employs multiple micro-electromechanical system (MEMS) mirrors in series to receive collimated light and direct the light to provide light having input angles corresponding to a desired field of view at a point or line at an incoupler (IC) of a waveguide without an optical relay. An initial one or more MEMS mirrors accepts collimated light and generates the scan angles. A last MEMS mirror in the series scans at a range of angles p...
