Abstract
Embodiments of the disclosure provide a system for controlling power of laser lights emitted by an optical sensing device. The system includes at least one storage device configured to store instructions and at least one processor communicatively coupled to the at least one storage device and configured to execute the instructions to perform operations. The operations include detecting an object within a field of view of the optical sensing device based on a reflected laser signal received by the optical sensing device, determining a distance of the object from the optical sensing device, determining a value indicating a total power of one or more laser beams to be incident on an aperture at the distance, and comparing the value with a predetermined tolerance value. The operations also include adjusting a laser emission scheme to reduce the total power when the value is greater than the predetermined tolerance value.
