H-S波前传感器时域采样频率对探测误差的影响

Influence of Time Domain Sampling Frequency for H S Wavefront Sensor on Detection Error

波前传感器是自适应光学系统的重要组成部分。讨论了ＨａｒｔｍａｎｎＳｈａｃｋ（ＨＳ）波前传感器的采样频率对探测误差的影响，理论分析结果说明，时域采样频率引入的探测误差是ＨＳ波前传感器的重要误差源，其大小随时域采样频率的增大而下降。

Wavefront sensor is an important part of an adaptive optical system.The influence of sampling frequency for Hartmann Shack wavefront sensor on detecting error is discussed.The theoretical analyzing results show that the detecting error introduced by time domain sampling frequency is an important error source for H S wavefront sensor.The size of detecting error varies with sampling frequency.
