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.   Numerical simulations for adaptive optics system (EI CONFERENCE) 会议论文  OAI收割 31st Chinese Control Conference, CCC 2012, July 25, 2012 - July 27, 2012, Hefei, China 作者:  Wang X.-J. 收藏  |  浏览/下载：27/0  |  提交时间：2013/03/25 The simulation methods for the adaptive optics (AO) system are studied. Based on the global structure of the AO system  the key principles for each module are first discussed systematically  including the wave propagation principles  wave-front representation  coordinates transformation between the coordinates considered  wave-front reconstruction algorithm and DM principles. The purpose of these discussions is to establish the theoretical foundations for the numerical simulations of the AO system. Then the simulation steps are described in detail and a series of numerical simulation results are given which validate the effectiveness of our simulation work. 2012 Chinese Assoc of Automati.
