Speckle mitigation in laser projection systems

A method of operating a laser projection system comprising:

• operating a light source to emit at least one output beam;
• directing the output beam towards a selected one of a plurality of frame generating actuators;
• and
• generating at least a portion of a scanned laser image on the given projection surface by operating the light source for output emission of encoded image data and controlling the selected frame generating actuator to scan the output beam across a plurality of image pixels to define the image frame, wherein 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.

A method of operating a laser projection system comprising a light source and scanning optics comprising a plurality of frame generating actuators and an actuator selector, the method comprising:

• operating the light source for output emission of encoded image data in the form of at least one output beam;
• controlling the actuator selector to direct the output beam towards a selected one of the plurality of frame generating actuators;
• and
• controlling the selected frame generating actuator to scan the output beam across a plurality of image pixels to define an image frame, wherein 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.
