  • Publication number: 20230384428
    Abstract: A lidar system capable of automatically adjusting the optical power of an optical-probe beam thereof based on scan-rate measurements and/or detection of a person within the system's field of view. In an example embodiment, the automatic power-adjustment capability includes a capability of turning OFF the corresponding laser source, e.g., when the scanning mirror has stalled. In various embodiments, the scan rate may continuously be monitored using suitably positioned photodiodes, a position-sensing photodetector, or a two-dimensional, pixelated light sensor configured to receive light reflected from the scanning mirror. Depending on the specific embodiment, the reflected light may include a small portion of the optical-probe-beam light or may be generated using a separate dedicated light source.
