摘要
望远镜跟踪架的结构形式至关重要,它将影响整个跟踪系统的跟踪精度和快速响应等性能指标。本文介绍了望远镜跟踪架的三种结构形式—赤道式、地平式和水平式,通过建立赤道式、地平式和水平式坐标系,相应介绍了三种跟踪架的测量原理,对三种结构形式的跟踪架的特点进行了讨论分析,赤道式利用赤经轴的匀速转动抵消地球自转产生的星体的视运动,主要用于天文观测,地平式具有较好的承载能力,应用较为广泛,现代大口径望远镜均采用地平式结构,水平式无天顶盲区,对高仰角空域目标跟踪性能优异。
The structure of telescope is very important because it can affect tracking precision and frequent response for the whole tracking system. Three types of structure which are equatorial mount,altitude-azimuth mount and altitude-altitude mount for telescope are addressed. The equatorial coordinate,altitude-azimuth coordinate and altitude-altitude coordinate are established and the measure principles for three types of telescope structure are presented. The features of three types of structure are discussed in the paper. There is no field rotation for compensation of equably rotation of pole axis for the equatorial telescope which is suitable for astronomical observation. Altitude-azimuth telescope is extensively applied for perfect carrying capacity,and it is selected for all large telescopes resent years. There is no zenith blind spot for altitude-altitude telescope,and it is suitable for tracking high orbit targets.
