摘要
水平式望远镜经轴与纬轴的不垂直度直接影响到望远镜的指向误差,准确检测出望远镜两回转轴系的垂直度误差并加以修正是非常必要的。本文以某400 mm水平式望远镜为例,针对水平式望远镜经纬两轴的特点提出了一种经纬轴垂直度误差的光学检测方法。通过检测数据计算获得该水平式望远镜的经纬两轴垂直度误差为46″,分析出检测误差为11″,借助检测数据对实际测量数据进行修正后,达到了提高望远镜指向精度的目的。
Longitude and latitude shaft errors of horizontal telescope directly affect the pointing error. It is important to accurately measure the perpendicularity error of telescope shafts and amend it. Based on the characteristics of horizontal telescope shafts, an optical measurement method is presented for the errors of longitude axis and altitude axis perpendicularity. A 400 mm aperture horizontal telescope has been tested, and 46＂ perpendicularity error is calculated out from the measured data. Error analysis indicates that the optical measurement precision is 11＂. The actual data is accurately amended with the measured data, and the pointing precision is improved greatly.
