摘要： An invisible scanning safety system for use with laser projection systems that includes sensors monitoring less than the entire laser accessible region such that the region monitored is reduced to almost the absolute minimum, to thereby prevent unwarranted stoppages or disturbances in projection. The system may also monitor a 360 degree region around the lens of the laser projector, a wedge-shaped region, a pyramid-shaped region or a chimney-shaped region.
