摘要
介绍全日面太阳光学和磁场望远镜的自动跟踪与导行方法。本系统采用光栅钢带码盘作位置检测元件,实时计算太阳站心位置,构成高精度的位置环跟踪系统,并用视频CCD和胡氏导行光路进行太阳导行,提高了系统的长时间跟踪精度。最后经实测,分析得出该跟踪导行系统完全达到预期指标。
The telescope auto-tracking and guiding method for the full solar disk vector magnetograph telescope is introduced in this paper. The method offers a tape encoder for the location detection device and calculates the real-time topocentric position of the Sun, which constitutes a high-precision closed-loop tracking system. It also offers an CCD guiding system, enhancing tracking system prolonged accuracy. Finally, from the analysis of experimental data It is concluded that the tracking and guiding system fully meet anticipative indicators.
