SCANNING LASER PROJECTOR WITH SAFETY SYSTEM

A scanning projector includes a MEMS device with a scanning mirror that sweeps a light beam in two dimensions. A laser limit comparison circuit determines a metric from measured peak scan angles and measured light output. The metric is compared to a threshold and a light source is shut down when the...
