| 摘 要： | 云南天文台的太阳Stokes光谱望远镜是一台通过测量磁敏谱线的Stokes参数I,Q,U和V的轮廓来研究太阳磁场精细结构的光谱型矢量磁场测量仪。它利用4个完整的Stokes轮廓所蕴含的丰富信息,完全确定辐射的偏振状态,从而精确地测定太阳黑子区的矢量磁场。文章首先介绍了该望远镜的结构,进而详细地介绍了该望远镜所测量的偏振光谱资料的处理方法。

| Abstract: | The Solar Stokes Spectra Telescope at the Yunnan Observatory is a typical spectral vector magnetograph which can measure accurately the vector magnetic field of sunspots by using Stokes profiles, I, Q, u and V, of magnetic-sensitive lines. By using abundant message contained in the four Stokes profiles, it can determine the polarization state of radiation from the sunspots and measure accurately the vector magnetic field within sunspots. The structure of the telescope is described firstly. In the following, the process of the polarization spectra collected by the telescope is introduced in detail. |
