先进空间太阳天文台（ASO-S）上的有效载荷全磁盘磁仪（FMG）将测量光球中的矢量磁场。该仪器由一个前窗滤光片、一个望远镜、一个LCVR偏振计、一个稳像系统、一个7级可调Lyot滤光片、一个像素为4096×4096的CMOS相机和一对校准/对焦轮组成。在本文中，我们描述了FMG仪器的设计，并提供了用FMG原型进行的测试观察的总结。
The Full-disk MagnetoGraph (FMG), a payload onboard the Advanced Space Solar Observatory (ASO-S), will measure the vector magnetic field in the photosphere. The instrument consists of a front-window filter, a telescope, an LCVR polarimeter, an image-stabilization system, a seven-stage tunable Lyot filter, a CMOS camera with 4096×4096 pixels and a pair of calibration/focus wheels. In this paper, we describe the design of the FMG instrument and provide a summary of test observations carried out with the FMG prototype.
