摘    要:对夏克-哈特曼(Shack-Hartmann)波前传感器的相位探测误差进行了分析,并分析了它的政论相位探测极限,分析结果表明,夏克-哈特曼波前传感器的相位探测精度与探测器的噪声水平,探测目标的亮度有关,还与被探测对象的特性、孔径波前分割有关。给出了它们的关系表达式。

关 键 词:自适应光学  波前传感器  相位误差

Abstract:A theoretical analysis of the phase measurement performance of Shack-Hartmann wavefront sesnor is made based on the analysis of the subaperture centroid detecting error of atmospheric turbulence with Shack-Hartmann wavefront sensor.The phase detecting error of Shack-Hartmann wavefront sensor is not only dependent on the noise of detector,object′s stellar magnitude,but also the characteristics of object and the numbers of subaperture.A relationship of phase probe error of atmospheric turbulence with Shack-Hartmann wavefront sensor is presented in analytic form.
Keywords:adaptive optics    wavefront sensor    centroid detect    phase error
