Abstract
A near-eye display system employs a low-amplitude, low-frequency micro-electromechanical system (MEMS) mirror in series with a higher-amplitude, higher-frequency resonant MEMS mirror to rotate at a reduced amplitude and frequency with respect to the resonant MEMS mirror redistribute illumination pulses or pixels at the extents of a sinusoidal angular scan pattern of the resonant MEMS mirror.
