Description

[0001] technical field [0002] The invention relates to a fast correction method of a precision vibrating mirror correction system. Background technique [0003] In laser processing technology, the galvanometer is generally used to control the optical path to process various complex graphics and characters; due to environmental temperature and humidity interference, motor loss of steps, etc., the galvanometer will produce deviations after a certain period of time, resulting in In the process of processing, deviations are formed in the splicing between the areas scanned by the galvanometer and the product processing fails. At this time, error compensation must be performed on the galvanometer to reduce this deviation. [0004] The traditional technology is to make a matrix target on the calibration board, and then combine with auxiliary measuring equipment (such as the second element, etc.) to measure, manually calculate the deviation between theory and reality, and then gen...
