30m级光学/红外望远镜的宽视场多目标光谱仪

宽视场多目标光谱仪具有宽波段、多分辨率模式和高通光效率的特点,是极大望远镜终端仪器使用率最高的通用型仪器. 30 m级望远镜的宽视场多目标光谱仪因体量和成本急剧增加而面临重要挑战,同时天文学的不断发展对天文新技术的发展提出了更高的要求,尤其是多个巡天项目对于多目标光谱后随观测的迫切需求.综述了几类宽视场多目标光谱仪的发展现状,介绍了国际3架30 m望远镜宽视场多目标光谱仪概念设计的最新进展和仪器特点,着重介绍了中国参与研制的30 m望远镜(TMT)中的宽视场多目标光谱仪的相关进展.

Wide Field Multi-object Spectrograph for 30 m Class Optical/Near Infrared Telescope

Due to its wide wavelength coverage, multi-resolution mode, and high efficiency, wide field multi-object spectrograph become the work-horse general purpose instrument for the extremely large telescope. It''s still a great challenge to build wide field multi-object spectrograph for a 30 m class telescope with sharply increasing volume and budget. With the great development of astronomy and astrophysics, new astronomical technology is essentially required. In this paper, the research progress of different wide field multi-object spectrographs is illustrated and reviewed, especially with the introduction about the recent status of conceptual design and their instrument features from three 30 m class telescope international projects. It also introduces the current effort made by the China''s team to the TMT (Thirty Meter Telescope)-WFOS (Wide Field multi-Object Spectrograph).
