摘要:

高角分辨率单片光学和近红外积分场摄谱仪(HARMONI)是欧洲南方天文台的极大望远镜(ELT)的可见光和近红外(NIR),自适应光学辅助,积分场摄谱仪。它将具有单共轭自适应光学(SCAO)模式(使用单个明亮的自然导星)和激光层析自适应光学(LTAO)模式(使用多个激光导星),分别提供具有高性能和良好天空覆盖的近衍射极限超光谱成像。一个独特的高对比度自适应光学(HCAO)的能力,最近增加了系外行星的特性。HARMONI拥有8个HAWAII-4 RG阵列的大型探测器、4种光谱标度选择和11种光栅选择,分辨率范围从R~3000到R~17000,使其成为一种非常通用的仪器,可以满足广泛的观测计划。

英文摘要:

The High Angular Resolution Monolithic Optical and Near-infrared Integral field spectrograph (HARMONI) is the visible and near-infrared (NIR), adaptive-optics-assisted, integral field spectrograph for ESO's Extremely Large Telescope (ELT). It will have both a single-conjugate adaptive optics (SCAO) mode (using a single bright natural guide star) and a laser tomographic adaptive optics (LTAO) mode (using multiple laser guide stars), providing near diffraction-limited hyper-spectral imaging with high performance and good sky coverage, respectively. A unique high-contrast adaptive optics (HCAO) capability has recently been added for exoplanet characterisation. A large detector complement of eight HAWAII-4RG arrays, four choices of spaxel scale, and 11 grating choices with resolving powers ranging from R~3000 to R~17000 make HARMONI a very versatile instrument that can cater to a wide range of observing programmes.
