Abstract
A technique for managing image quality in a laser-based imaging system is provided. Laser light sources are organized into two or more groups, and optical output power of a light source group containing an under-performing laser is matched to that of the under-performing laser, while the optical output power of the light sources in the remaining groups is not. The output of the laser light sources in each group is interleaved with the output of the laser light sources in the other groups, so that perceptual uniformity of a displayed image is maintained when the display is viewed from an appropriate viewing distance.
