4米口径的丹尼尔K. Inouye太阳望远镜（DKIST）以前被称为先进技术太阳望远镜（ATST），目前正在夏威夷毛伊岛的Haleakaldae建造，预计将于2019年开始运营。建成后，DKIST将成为最大的地面太阳望远镜，提供前所未有的分辨率和光子收集能力。DKIST将配备一套一流的设施级仪器，提供独特的成像、光谱和分光偏振观测机会，覆盖可见光至红外波长范围。这套第一光仪器将包括：一个用于太阳大气层高空间和时间分辨率成像的可见光宽带成像仪;一个用于灵敏和准确的多线分光偏振测量的可见光分光偏振仪;一个用于高空间分辨率分光偏振测量的基于法布里-珀罗的可见光可调谐滤波器;光纤衍射限幅近红光偏振光谱仪（DL-NIRSP）用于二维高空间分辨率分光偏振分析（同时提供空间和光谱信息）;以及用于日冕磁场测量和盘上观测的低温近红外光谱偏振仪，CO谱线位于4.7 μm。我们将概述DKIST的独特功能，重点关注第一光仪器套件，强调支持瞬态和动态太阳现象观测的一些附加属性，并触及一些操作策略和DKIST关键科学计划。（© 2016 WILEY-VCH Verlag GmbH & Co.

The 4-m aperture Daniel K. Inouye Solar Telescope (DKIST) formerly known as the Advanced Technology Solar Telescope (ATST) is currently under construction on Haleakalā (Maui, Hawai'i) projected to start operations in 2019. At the time of completion, DKIST will be the largest ground-based solar telescope providing unprecedented resolution and photon collecting power. The DKIST will be equipped with a set of first-light facility-class instruments offering unique imaging, spectroscopic and spectropolarimetric observing opportunities covering the visible to infrared wavelength range. This first-light instrumentation suite will include: a Visible Broadband Imager (VBI) for high-spatial and -temporal resolution imaging of the solar atmosphere; a Visible Spectro-Polarimeter (ViSP) for sensitive and accurate multi-line spectropolarimetry; a Fabry-Perot based Visible Tunable Filter (VTF) for high-spatial resolution spectropolarimetry; a fiber-fed Diffraction-Limited Near Infra-Red Spectro-Polarimeter (DL-NIRSP) for two-dimensional high-spatial resolution spectropolarimetry (simultaneous spatial and spectral information); and a Cryogenic Near Infra-Red Spectro-Polarimeter (Cryo-NIRSP) for coronal magnetic field measurements and on-disk observations of, e.g., the CO lines at 4.7 μm. We will provide an overview of the DKISTs unique capabilities with strong focus on the first-light instrumentation suite, highlight some of the additional properties supporting observations of transient and dynamic solar phenomena, and touch on some operational strategies and the DKIST critical science plan.
