USO太阳矢量磁象仪的相位III
Phase III of USO Solar Vector Magnetograph
摘要：
太阳矢量磁力仪（SVM）是安装在乌代布尔太阳天文台（USO）的现代成像分光偏振仪。在早期阶段，使用现成组件和内部软件开发开发了仪器。随后，对分系统的光机设计和望远镜跟踪系统进行了改进。仪器开发的第三阶段有三项重大改进，其中包括：（一）安装了内部开发的基于网络摄像机的望远镜引导系统，（二）使用液晶可变延迟器和快速CCD摄像机的高节奏分光偏振测量法，以及（三）将Na D1线与规则光球Fe 630.2 nm线结合起来，用于色球观测。
英文摘要：
The Solar Vector Magnetograph (SVM) is a modern imaging spectropolarimeter installed at Udaipur Solar Observatory (USO). Earlier phases saw the development of the instrument using off-the-shelf components with in-house software development. Subsequently, improvements were done in the opto-mechanical design of the sub-systems and the telescope tracking system. The third phase of the instrument development saw three major improvements, these include: (i) installation of a web-camera based telescope guiding system, developed in-house, (ii) high-cadence spectropolarimetry using Liquid Crystal Variable Retarders and a fast CCD camera and (iii)inclusion of Na D1 line with regular photospheric Fe 630.2 nm line for chromospheric observations.
