针对激光振镜在机械零件快速成型中出现的线性失真和非线性失真，提出了一种激光振镜的图形校正算法。利用该算法一方面可以消除激光振镜在图形扫描中出现的线性失真和非线性失真；另一方面可以校正激光振镜扫描过程中产生的综合误差。实验表明，通过该算法消除了产生的线性失真和非线性失真并且校正了产生的综合误差，为激光振镜在机械零件快速成型制造中提供了满意的校正效果。

Aimed at the linear distortion and nonlinear distortion appeared in laser galvanometer in mechanical parts in rapid pro-totyping,a laser galvanometer graphic correction algorithm was proposed. With using of this algorithm,on one hand,the distortion of linear laser galvanometer appeared in graphic scanning and in that of nonlinear could be eliminated,and on the other hand,compre-hensive error produced in laser galvanometer scanning process could be corrected. Experiments show that the algorithm eliminates the linear and nonlinear distortion generated,and corrects the integrated error produced,which provides satisfactory correction effect for the laser galvanometer in rapid prototyping manufacturing machinery accessories.
