摘要
红外太阳望远镜中的光电导行系统是高精度的反馈跟踪系统。在开环控制下,难以实现太阳望远镜的跟踪指标,所以必须使用光电导行作为目标位置反馈系统。但是在地平式系统跟踪过程中,光电导行望远镜中的像场会旋转,如果不进行消旋,光电导行系统就不能工作,这就需要解决光电导行系统中的像场旋转。本文在理论上分析了红外望远镜中光电导行系统的像场旋转,并给出了像在CCD面上的运动变化公式。
The Auto Guide Unit of the solar telescope is a feedback track system with high precision.Under the open loop control,it is difficult to reach tracking demand of the solar telescope;therefore,it is necessary to use the autoguide unit as the feedback control system for the target position.In the process of tracking,there is an image rotation of the autoguide unit,and if the effect of the image rotation is not considered,it can disable the autoguide unit,therefore it s necessary to resolve the image rotation of the autoguide unit.In this paper,the analysis of image rotation about the autoguide unit of the solar telescope has been given theoretically,and the specific formula of the movement about the image in the CCD has been worked out.
