Multiple laser drive method, apparatus and system |
摘要 |
A scanning projector includes a scanning mirror that sweep a beam in two dimensions. The beam is created by multiple laser light sources, at least two of which create light at substantially the same wavelength. A first of the two light sources is driven up to a transition point past which both of the two light sources are driven (equally or unequally). |

1. A scanning laser projector comprising:
a scanning mirror to reflect a light beam in a raster pattern to display an image; a plurality of laser light sources that emit light at substantially the same wavelength to form the light beam; and a controller coupled to receive a commanded light output level and to drive the plurality of laser light sources, the controller configured to drive only a first of the plurality of laser light sources when the commanded light output level is below a transition output light level, and to drive the first and a second of the plurality of laser light sources when the commanded light output level is above the transition output light level. |
