The LBT is currently one of the world's most advanced optical telescopes; using two 8.4 m (27 ft) wide mirrors, with a 14.4 m center-center separation, it has the same light gathering ability as an 11.8 m (39 ft) wide single circular telescope and detail of a 22.8 m (75 ft) wide one. Either of its mirrors would be the second-largest optical telescope in continental North America, behind the Hobby–Eberly Telescope in West Texas; as of summer 2014, it would still be the largest ''monolithic'', or , in an optical telescope. Optical performance of the telescope is excellent, and Strehl ratios of 60–90% in the infrared H band and 95% in the infrared M band have been achieved by the LBT.〔 == Project == The LBT was originally named the "Columbus Project". It is a joint project of these members: the Italian astronomical community represented by the Istituto Nazionale di Astrofisica, the University of Arizona; University of Minnesota, University of Notre Dame,〔 University of Virginia,〔 the LBT Beteiligungsgesellschaft in Germany (Max Planck Institute for Astronomy in Heidelberg, Landessternwarte in Heidelberg, Leibniz Institute for Astrophysics Potsdam (AIP), Max Planck Institute for Extraterrestrial Physics in Munich and Max Planck Institute for Radio Astronomy in Bonn); The Ohio State University; Research Corporation in Tucson. The telescope design has two mirrors mounted on a common base, hence the name "binocular".〔 LBT takes advantage of active and adaptive optics, provided by Arcetri Observatory. The collecting area is two 8.4 meter aperture mirrors, which works out to about 111 m2 combined. This area is equivalent to an circular aperture, which would be greater than any other single telescope, but it is not comparable in many respects since the light is collected at a lower diffraction limit and is not combined in the same way. Also, an interferometric mode will be available, with a maximum baseline of for aperture synthesis imaging observations and a baseline of for nulling interferometry. This feature is along one axis with the LBTI instrument at wavelengths of 2.9–13 micrometres, which is the near infrared. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Large Binocular Telescope」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
