摘要：
Galvanometri scanner is widely used in rapid prototyping systems. Due to the intrinsic nonlinear relationship between the deflection angles and the corresponding xy coordinates, the pillow-shaped field distortion would be introduced. In the paper, the aberration mechanism is analyzed and the correction algorithm to compensate for the field distortion is proposed.
