HARMONI被认为是欧洲极大望远镜（E-ELT）的主力可见光和近红外（0.47-2.45微米）积分场摄谱仪。它提供了在几个光谱分辨率（R= 4000，10000，20000）的视宁度和衍射极限观测。HARMONI可以与几乎任何风格的AO（例如GLAO，LTAO，SCAO）一起工作，并配备了四个空间尺度（4，10，20和40 mas），因此可以针对各种科学计划进行优化配置，从点源的超灵敏观测到扩展对象的高角分辨率空间分辨研究。在本文中，我们描述了该仪器的预期性能以及其科学潜力。我们显示了一些模拟观测选定的科学计划，并比较HARMONI与其他地面和空间为基础的设施，如VLT，阿尔马，和JWST，评论他们的协同作用和互补性。
HARMONI has been conceived as a workhorse visible and near-infrared (0.47-2.45 microns) integral field spectrograph for the European Extremely Large Telescope (E-ELT). It provides both seeing and diffraction limited observations at several spectral resolutions (R= 4000, 10000, 20000). HARMONI can operate with almost any flavor of AO (e.g. GLAO, LTAO, SCAO), and it is equipped with four spaxel scales (4, 10, 20 and 40 mas) thanks to which it can be optimally configured for a wide variety of science programs, from ultra-sensitive observations of point sources to highangular resolution spatially resolved studies of extended objects. In this paper we describe the expected performance of the instrument as well as its scientific potential. We show some simulated observations for a selected science program, and compare HARMONI with other ground and space based facilities, like VLT, ALMA, and JWST, commenting on their synergies and complementarities.
