Abstract

磁场测量是太阳科学观测中最重要的一部分,围绕磁场展开的相关研究是太阳物理的研究热点。磁像仪是一种可以进行高分辨磁场观测的精密测量器件,在地基和空间太阳观测中得到广泛的应用。窄带可调谐滤光器是磁像仪获得窄带光的核心光学部件,其特性会对磁像仪的性能产生影响。滤光器分为两大类,具体可包括四种结构,具有不同的性能特征,可根据磁像仪的需求进行选择。本文调研了国内外著名地基、球载、空间太阳磁场望远镜,总结了太阳磁像仪中常用的各种窄带可调谐滤光系统的实现方式,滤光器的结构、原理、轮廓特性以及在磁像仪中的应用场景,归纳了不同太阳磁像仪滤光系统的设计特点和关键技术。本研究能够对未来太阳磁像仪滤光系统的研制提供参考。
