Abstract
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 proportional to the scan angles generated by the initial MEMS mirror(s) and directs the scanned light back to a spot or a line at the IC.
