| 英文摘要 | A line-of-light projecting module is illuminated by a diode-laser bar (22) and includes light-pipe (16) for homogenizing light from the diode-laser bar in the slow-axis (x). 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 (x) and as a collimated beam in the fast-axis (y). The light propagates through the light-pipe (16) unguided in the fast-axis (y). The light is guided by the light-pipe (16) in the slow-axis (x) , and homogenized in the slow-axis (x) by making multiple reflections from walls of the light-pipe (16). An anamorphic projection optics (18) assembly projects the light from the exit end of the light-pipe and focuses the light to form the line-of-light (20). A cylindrical lens (26) may form parallel light along the fast axis (y) and a microlens array (50) may reduce the divergence along the slow axis (x). A telescope (54) may reduce the dimensions of the light-pipe (16) by decreasing the distance between the beams emitted from the diode-laser bar (22). |
