Abstract
The subject matter of this disclosure relates to a system, a method, and an apparatus for power monitoring and blockage detection in a lidar device. An example method includes: emitting, by a transmitter of a lidar device, an optical signal toward a maintenance area that is inside the lidar device and outside a field of view for the lidar device; measuring, by a power monitoring circuit of the lidar device, an intensity of an incident signal corresponding to the optical signal; comparing the measured intensity with a target intensity value; and adjusting, based on the comparison, an electrical control signal provided to the transmitter.
