要：主要讨论了用传统的补偿畸变的方法校正振镜二维扫描光学系统中图形畸变后，为进一步提高精度，利用图像处理技术，进行二次闭环误差校正，使在10mm×10mm的加工平面内，校正后的精度优于3μm。<br /> By using traditional method, dual-galvanometric laser scanning manufacturing errors is reduced, but for farther precision improving, a new method, which use image processing is introduced. Through the second closed-loop error revision,the precision is better than 3 μm in the area of 10 mm × 10 mm working face.<br /> 关键词：激光加工 振镜扫描 加工误差 图像处理<br /> laser manufacturing ; galvanometric
