| 摘 要： | 本文针对大天区面积多目标天文望远镜的要求,提出了一种高分辨率光谱仪的设计方案。它采用WHITEPUPIL型结构形式的光学系统,用焦面芯径变换法来压缩光纤芯径,从而使整个光学系统的结构大大缩小。光纤的输出端交错排列成两排,可以同时检测150个目标的光谱信息。

| Abstract: | A high resolution spectrometer is designed for use at the White-Pupil of the LAMOST 4-meter telescope.In this spectrometer,with the method of Focus-Plane Fibre Core Diameter Change,light out of a 300 symbol 109f "Symbol" s 12μm fibre is transfer to 7 fibres which core diameter is 120 symbol 109f "Symbol" s 12μm So,the dimensiom of this spectrometer is decreased.At the outputs of end the fibres are arranged in two line.150 objects can be detected at one time. |
