Abstract: A scanning projector and method is provided that that uses at least one multi-stripe laser to generate the laser light for the scanned image. Specifically, the multi-stripe laser includes at least a first laser element and a second laser element formed together on a semiconductor die. The first laser element is configured to output a first laser light beam, and the second laser element is configured to output a second laser light beam. At least one scanning mirror is configured to reflect the first laser light beam and the second laser light beam, and a drive circuit is configured to provide an excitation signal to excite motion of the at least one scanning mirror. Specifically, the motion is excited such that the at least one scanning mirror reflects the first laser light beam and the second laser light beam in a raster pattern of scan lines.

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.
