摘要
基于互相关因子和绝对差分算法以及哈特曼夏克波前传感器的基本原理 ,根据室内模拟太阳米粒结构研究了低对比度扩展目标情况下应用相关哈特曼夏克波前传感器探测波前误差的可行性。结果表明 。
Based on cross-correlation and absolute difference algorithms and the principle of Hartmann-Shack wavefront sensor, the feasibility of correlating Hartmann-Shack wavefront sensor used for low-contrast and extended object is studied according to the indoors solar granulation simulator. The results show that correlating Hartmann-Shack wavefront sensor can be efficiently used to detect wavefront aberration for low-contrast and extended object.
