Abstract:
A scanning laser projector detects obstructions in a projector field of view using a proximity detector that detects infrared light at a photodetector. The photodetector is tested with an additional infrared light source. The additional infrared light source may also be used as proximity detector that can detect a local obstruction blocking the photodetector.
