太阳磁场遥感的新技术现在提供了高角度分辨率和高精度的太阳大气层内磁场矢量测量。这些测量使人们能够对太阳大气层中的磁过程和现象有更深入的物理了解，这些过程驱动着太阳辐射和微粒输出的变化。新技术在这里审查的背景下，他们促进了科学进步。重点是推断场矢量的技术。探索太阳现象所需信息的定量性质严重限制了观测所需的精度和角分辨率。本文对这些要求进行了评述，并沿着评估了未来观测能力的改进将如何满足这些要求。人们也可以将我们对太阳磁场的理解的最新进展大部分归因于作为太阳磁力测量基础的偏振测量分析技术的不断进步。并对分析技术的现状和前景进行了评述。
New techniques for remote sensing of solar magnetic fields now provide measures of the magnetic field vector within the solar atmosphere with high angular resolution and high precision. These measurements have enabled a much improved physical understanding of magnetic processes and phenomena in the solar atmosphere, processes that drive the variability of the Sun's radiative and particulate output. The new techniques are reviewed here in the context of the scientific advances they have fostered. Emphasis is given to techniques for inferring the field vector. The quantitative nature of the information needed to explore the solar phenomena sharply constrains the needed precision and angular resolution of the observations. These requirements are reviewed here, along with an assessment of how future improvements in observing capabilities will address these requirements. One may also attribute much of the recent advance in our understanding of solar magnetic fields to ongoing progress in techniques for analysis of the polarization measurements that underlie solar magnetometry. The status and prospects of analysis techniques are also reviewed.
