Description

technical field [0001] The invention relates to the field of laser technology. More specifically, it relates to a method for calibrating an aiming point of a power grid foreign object laser cleaning device. Background technique [0002] The usual cleaning objects of the power grid foreign matter laser cleaning device are small centimeter-sized clothing such as branches, cloth strips, and nylon ropes. In order to meet the cleaning energy requirements, the diameter of the laser spot irradiated to the cleaning object must be less than 1cm. The working distance of the power grid foreign matter laser cleaning device is usually 100 to 200 meters. In order to achieve effective cleaning of the cleaning object, the laser beam needs to be accurately aimed at the cleaning object, and the aiming accuracy is required to reach 20-50μrad. Therefore, the power grid laser foreign body removal system has higher requirements on the accuracy of the aiming point. [0003] The existing aiming p...
