The methods obtaining the flat-field by a vector scanning are discussed in this paper. After the geometry analysing,it comes to the following conclusion, the defocus can be completely eliminated,but a remnant distortion is existed in pre-objective scanning. The post-objective scanner using a line-translator can only be used in a small field, but it can not correct the scanning distortion.

The methods obtaining the flat-field by a vector scanning are discussed in this paper. After the geometry analysing,it comes to the following conclusion, the defocus can be completely eliminated,but a remnant distortion is existed in pre-objective scanning. The post-objective scanner using a line-translator can only be used in a small field, but it can not correct the scanning distortion. The correction formulas of a remnant distortion in pre-objective scanning are presented. The limits of dynamic focus are extended using the optical leverage. Thin-lens design equations and distortion correct formulas for post-objective scanning are presented.

介绍了激光矢量扫描获得平视场的方法;进一步导出了在前置扫描中残余畸变的校正公式、在后置扫描中扩大直线转换器动态聚焦范围的光学设计公式和扫描畸变的校正公式.通过对二维振镜矢量扫描的几何分析,得出下列结论:使用线性扫描物镜的前置扫描虽能消除离焦,但存在扫描的残余畸变;使用直线转换器的后置扫描只能用于小视场离焦校正,对扫描畸变并无校正作用

In the process of stereolithography(SL),layers of liquid resin are successively cured by UV laser until the model's final shape is obtained.In the growth process,which is from dot to trace,from trace to area,and from 2D to 3D,a large number of vector scanning must be carried out,consequently,reasonable scanning paths can increase the productivity and the service life of the scanner.In this paper,a laser scanning path generating algorithm is proposed,which is well used in our SL machine.

在立体光固化(SL)快速成型中,零件是靠激光逐层扫描光敏树脂固化成型的.在由点到线、由线到面、由二维到三维的逐层累积过程中,扫描器要做大量的扫描.因而合理的扫描路径对提高成型效率无疑有重要意义;另外合理的扫描路径还能改善扫描器的工作状态,明显提高扫描器的使用寿命.本文提出了一种简捷有效的扫描路径生成算法,成功地应用于开发的快速成型机中.
