摘要

波前探测器是自适应光学系统的一个关键部分

用来探测由于大气湍流引起的入射光波前畸变。本文通过分析和比较

选用ICCD形式的Shack-Hartmann波前探测器

作为人造信标自适应光学系统的波前探测器。理论分析与实验结果表明:探测器的动态范围与微透镜口径、焦距及探测器工作波长有关;影响探测器波前探测精度的因素有光量子起伏噪声、探测器读出噪声和探测器中光学系统成像质量。

Abstract

Wavefront sensors

one of key parts of Adaptive optical System

are used to measure wavefont distortion induced by atmosphere turbulence and So on. In this thesis.several kinds of wavefront sensors

which can be used in the Adaptive optical Systern

are compared and analyxed

and the ICCD Shack-Hartmann wavefront sensor is chosen far the Laser Guide Star Adaptive optics System. According to the theoretical analyses and experimental results

the dynamic range is relative to the diameter and focal length of the lenslet and detecting wavelength. The factors affecting on the accuracy are photon noise

readout noise and duality of the lens of the sensor.
