Scanning laser projector with safety system |
摘要 |
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 metric exceeds the threshold.
