SCANNING LASER PROXIMITY DETECTION |
摘要 |
A scanning laser projector (100) detects obstructions in a projector field of view using a proximity detector that detects infrared light at a photodetector (152). The photodetector is tested with an additional infrared light source (164). The additional infrared light source may also be used as proximity detector that can detect a local obstruction blocking the photodetector. |
