The traditional tandem Wadsworth mounting is originally designed to match the coaxial telescope and large-scale imaging spectrometer. When it is used to connect the off-axis telescope such as off-axis parabolic mirror  it presents lower imaging quality than to connect the coaxial telescope. It may also introduce interference among the detector and the optical elements as it is applied to the short focal length and small-scale spectrometer in a close volume by satellite. An advanced tandem Wadsworth mounting has been investigated to deal with the situation. The Wadsworth astigmatism-corrected mounting condition for which is expressed as the distance between the second concave grating and the imaging plane is calculated. Then the optimum arrangement for the first plane grating and the second concave grating  which make the anterior Wadsworth condition fulfilling each wavelength  is analyzed by the geometric and first order differential calculation. These two arrangements comprise the advanced Wadsworth mounting condition. The spectral resolution has also been calculated by these conditions. An example designed by the optimum theory proves that the advanced tandem Wadsworth mounting performs excellently in spectral broadband. 2012 Optical Society of America.   Position Detection of one Arc Permanent-Magnet Synchronous Motor in Telescope Mount Driving Based on High Frequency signals Injection 会议论文  OAI收割 Yantai, China, 2011-8-27 作者:  Xiaoli Song;  Zhenchao Zhang;  Di Wang;  Xiejia Lin 收藏  |  浏览/下载：44/0  |  提交时间：2014/01/08 HFsignals  sensorless  PMSM  simulation  telescope mount driving   Introduction of a 2.5m telescope mount and its performance 会议论文  OAI收割 San Diego, California, USA, 2010-6-27 作者:  Shihai Yang;  Guomin Wang;  Bozhong Gu;  Yuefei Wang;  Dongsheng Niu 收藏  |  浏览/下载：26/0  |  提交时间：2014/01/03 telescope  mount  structure   Introduction of a 2.5m telescope mount 会议论文  OAI收割 Marseille, France, 2008-6-23 作者:  Guomin Wang;  Bozhong Gu;  Jiang Xiang 收藏  |  浏览/下载：22/0  |  提交时间：2014/01/01 astronomy  telescope  telescope mount  structure design   Mount control system for CFGT telescope 会议论文  OAI收割 Orlando, FL, 2006-5-24 作者:  Xinqi Xu;  Wangping Zhou;  Zhiming Dong 收藏  |  浏览/下载：22/0  |  提交时间：2013/12/28 giant telescope  control system  mount drive  LAMOST  CFGT
