CCD在太阳磁场测量中的应用

CCD is sun magnetic field measurement

本文描述了太阳磁场测量仪器由光电磁像仪到视频矢量磁像仪的发展过程。从观测的信息量的概念上来看，存在着面、点、面的发展过程；从观测的信息灵敏度来看，向高时间、高空间和高光谱分辨率的方向发展。同时本文论述了ＣＣＤ的三种高分辨率、大信息量、宽光谱区、面光源的太阳磁场观测技术。本文最后还对红外ＣＣＤ、紫外ＣＣＤ、弱光ＣＣＤ在太阳磁场测量和太阳恒星磁场观测的应用进行了介绍。

The development procedure of a sun magnetic field measurement device from optoelec-tronic magnetic spectrometer to video-vector magnetic spectrometer is related.As viewed from the amount of observed information,the development process is from face to point and from point to face;as viewed from the sensitivity of information,the trends will be high time-resolution,high space-reso-lution and high spectrum-resolution. Using CCD,three observating technigues of sun magnetic field are related at the same time.They have high resolution,large amount of information,wide spectrum and an area optical source.In the end, the applications of infrared CCD, ultraviolet CCD and weak-light CCD in the observation of sun magnetic field and sun stellar magnetic field are introduced.
