| 摘 要： | 提出了一种滚转角误差测量的新方法,该测量方法能够实现与其他自由度误差测量相集成,构成多自由度同时测量系统.系统采用带温控的半导体激光器单模光纤组件作为光源,有效降低了激光器本身的光线漂移,为测量提供高精度高稳定性的基准光线;采用特殊棱镜作为测量的敏感单元,通过此棱镜出射光线的直线度测量,间接实现滚转角误差测量.实验过程和数据表明,测量系统具有很好的稳定性和重复性,通过与电子水平仪的对比实验,验证了该方法的可行性,测量精度约为2".

| Abstract: | A roll-angle error measurement method which can be integrated with other parameters measurement system is proposed. The light source,single-mode fiber-coupled laser module with thermo-electric cooler (TEC) is used to decrease the laser beam drift,and provide reference beam for accurate and stable measurement. A special prism is used as a sensitive part,and the roll-angle error is obtained through straightness error of the two beams from the special prism. The experimental procedures and results are presente... |
