Abstract
A display system includes a first light source, a second light source, at least one movable mirror, and an attenuator. The first light source is configured to provide a first light in a first optical path. The second light source is configured to provide a second light in a second optical path. A portion of the second optical path overlaps the first optical path in an overlapping portion. The attenuator is positioned in at least the first optical path and configured to attenuate at least the first light. The movable mirror is movable to deflect the overlapping portion.
