Dual frequency and nematic LC materials were reported to be used in astronomical observations. However  nematic LC with its simple producing and driving method and multi-gray-level is promising in the application. We have investigated the nematic LC AO system and promoted its application for nearly ten years. Here  we reported our newest nematic LC AO system with bandwidth result of 3dB is 54.4 Hz  0dB bandwidth is 79.1Hz. 2012 IEEE.   An experimental indoor phasing system based on active optics using dispersed Hartmann sensing technology in the visible waveband 期刊论文  OAI收割 Research in Astronomy and Astrophysics, 2011, 卷号: 11, 期号: 9, 页码: 1111–1122 作者:  Yong Zhang;  Gen-Rong Liu;  Yue-Fei Wang;  Ye-Ping Li;  Liang Zhang 收藏  |  浏览/下载：23/0  |  提交时间：2014/01/08 astronomical instrumentation  active optics  adaptive optics   Preparing first light of LAMOST 会议论文  OAI收割 Marseille, France, 2008-6-23 作者:  Xiangqun Cui 收藏  |  浏览/下载：25/0  |  提交时间：2014/01/01 Large astronomical telescope  Wide field of view  Active optics  Segmented mirror  Multi-fiber spectroscopy survey
