ABSTRACT:
In an illumination system the radiation from one or more laser arrays is directed into a light pipe. The light pipe mixes the individual radiation contributions from the laser arrays and forms a uniform illumination line. The pointing direction of each of the laser arrays is monitored and controlled to preserve the brightness of the composite illumination line.
