Abstract:
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).
