Abstract

The invention is applicable to the technical field of laser processing, and provides a precision vibration mirror correction system and a precision vibration mirror correction method. The vibration mirror correction system comprises a vibration mirror correction target, a charge coupled device (CCD) image acquisition device, a two-dimensional motion platform device and a correction processing module, wherein an appointed mark point is marked on the correction target by a vibration mirror scanning module through laser reflection; the CCD image acquisition device performs image acquisition on a standard mark point marked by a vibration mirror; the two-dimensional motion platform device executes a high-precision positioning motion so as to guarantee the positioning precision; and the correction processing module calculates an image acquired by the CCD image acquisition device, finds out a position deflection of the mark point of the vibration mirror correction target and generates a vibration mirror compensation file to correct the vibration mirror. The vibration mirror correction system can realize high-precision correction of the vibration mirror conveniently and quickly.

Description

Technical field [0001] The invention belongs to the technical field of laser processing, and specifically relates to a precise galvanometer correction system and a correction method. Background technique [0002] In the field of laser processing, a large number of galvanometers are used for scanning processing. Due to the installation of galvanometers and various other reasons, the processed images in the scanning area will be deformed. However, the traditional manual measurement method is difficult to achieve 0.1 Positioning accuracy below mm. [0003] The publication date is August 26, 2009. The Chinese invention patent application with the application number 200910105786.2 discloses a galvanometer correction system and a correction method. The method uses a CCD image acquisition device to position the matrix target, and uses the correction processing module to output Compensation file for galvanometer. [0004] Compared with the traditional manual correction method, this method ...
