Abstract
In described examples, a DMD includes micromirrors. A first light source generates a first beam profile illuminating a first set of micromirrors of the DMD. A second light source generates a second beam profile illuminating a second set of micromirrors of the DMD. The first and second beam profiles partially overlap on at least some micromirrors of the DMD. The first light source is source-modulated independently of the second light source for adjusting power and brightness in response to a sensed driving condition. The micromirrors of the DMD are modulated in response to the sensed driving condition.
