1. A laser projection system comprising a light source and scanning optics wherein:

  • the scanning optics comprises a plurality of frame generating actuators and an actuator selector;

    the light source comprises at least one laser configured to emit an output beam;

    the actuator selector is positioned in an optical path of the output beam and configured to direct the output beam towards a selected one of the plurality of frame generating actuators;

    each of the frame generating actuators is configured to scan the output beam across a given projection surface to generate an image frame; and

    the frame generating actuators are spatially separated such that output beams scanned by the frame generating actuators illuminate each common pixel portion of the image frames at a different incidence angle.
