1. A near-eye display system comprising:
a waveguide having an incoupler (IC); and
multiple micro-electromechanical system (MEMS) mirrors in series to receive collimated light and direct the light to one or more input angles at a point or a line at the IC independent of an optical relay, wherein an initial MEMS mirror and a second MEMS mirror in the series are co-planar and the scanned light generated by the initial MEMS mirror reflects off a reflective surface of the waveguide to the second MEMS mirror.
