The state of the art for Liquid crystal adaptive optics in astronomical applications

摘要：

In this paper, we summarize the researches of liquid crystal (LC) adaptive optics(AO) in astronomical applications. 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.
