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.
