Abstract
System including first and second light sources and controller. First light source is configured to generate first light beam of first perceived color. Second light source is configured to generate second light beam of different second perceived color. Controller is configured to direct light from first light beam to an image projector during first time intervals and to direct light from second light beam to an image projector during second time intervals. First light source generates first light beam with first intensity. Second light source generates second light beam with different second intensity. Controller is configured to temporally interleave first and second time intervals such that second time intervals are longer than first time intervals. Method also provided.
