ABSTRACT:
A line-of-light projecting module is illuminated by a diode-laser bar and includes light-pipe for homogenizing light from the diode-laser bar in the slow-axis. A shaping optics assembly directs the light emitted by the diode-laser bar into the entrance end of the light-pipe as a diverging beam in the slow-axis and as a collimated beam in the fast-axis. The light propagates through the light-pipe unguided in the fast axis. The light is guided by the light-pipe in the slow-axis, and homogenized in the slow-axis by making multiple reflections from walls of the light-pipe. An anamorphic projection optics assembly projects the light from the exit end of the light-pipe and focuses the light to form the line-of-light.
