Description

technical field [0001] The invention relates to the technical field of laser vibrating mirrors, in particular to a laser vibrating mirror correction system and a laser vibrating mirror correction method. Background technique [0002] At present, the scanning galvanometer has become the mainstream technology in the field of laser marking because of its excellent performance. With the improvement of processing density and the increase of processing width, higher requirements are put forward for the precision of the whole machine. [0003] Usually, various nonlinear errors caused by the introduction of the galvanometer system are difficult to eliminate. With the expansion of the marking area, various geometric distortions become more prominent, which seriously affects the processing accuracy of laser marking. The commonly used calibration method in the prior art is to let the galvanometer mark a matrix target, then collect the coordinates of the points on the target, and perfo...
