The volume and the weight of the mirror that shakes among the first optical path system 300 reduce in the laser cleaning head to and the volume and the weight of the mirror that shakes of second optical path system 400 reduce, make the weight of laser cleaning head lighter, the volume is littleer, more does benefit to artifical handheld operation, promotes the cleaning efficiency.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
