摘要:

本文总结了Pic du Midi炮塔穹顶在光谱或成像模式下采用的光谱偏振测量方法。这些偏振计与光谱仪可通过塞曼效应绘制高空间分辨率的太阳磁场图,或通过汉勒效应测量宁静太阳中未分辨的湍流磁场。本文介绍了2003年以来投入使用的各版本偏振计的光学性能,并展示了利用CaII K 3933.7 Å谱线开展磁场分析的新结果。

英文摘要:

We summarize in this paper the spectro-polarimetric methods used at the Pic du Midi Turret Dome in spectroscopic or imagery mode. The polarimeters and spectrograph allow the cartography of solar magnetic fields at high spatial resolution through the Zeeman effect or measurements of the unresolved turbulent magnetic fields in the quiet Sun through the Hanle effect. We describe in this paper the optical capabilities of the successive versions of the polarimeters operating since 2003, and we present new results of magnetic field analysis with the CaII K 3933.7 Å spectral line.
