Abstract
A scanning projector includes one or more scanning mirrors that reflect a light beam to create an image. The beam is created by multiple laser light sources, at least two of which create light at substantially the same color. The multiple laser light sources are used alternately to illuminate successive pixels, lines, and/or frames. Speckle reduction is achieved because of spatial overlap of the light beams produced by the multiple laser light sources.
