US Patent 11567182 LiDAR safety systems and methods

Embodiments discussed herein refer to LiDAR systems and methods that monitor for fault conditions that could potentially result in unsafe operation of a laser. The systems and methods can monitor for faulty conditions involving a transmitter system and movement of mirrors in a scanning system. When a fault condition is monitored, a shutdown command is sent to the transmitter system to cease laser transmission. The timing by which the laser should cease transmission is critical in preventing unsafe laser exposure, and embodiments discussed herein enable fault detection and laser shutoff to comply with laser safety standards.
