摘要
论述了一种新型的机器人视觉系统所用激光准直光束的获取方法 ,分析了半导体激光束的像散椭圆高斯光束特性 ,设计了光束准直系统的光学结构 ,利用光斑法对准直度进行了检验 ,实验证明利用这种方法获取的准直光束符合该视觉系统的要求。
The realized method of collimated coherent light beam for a novel robot vision system is presented. The properties of astigmatism ellipse Gauss beams of the semiconductor laser are analyzed. An optical structure of collimating system is designed. The collimation degree is tested by facula method. The experiments show the collimating device is suitable for the novel robot vision system.
