摘要: 提出了一种自适应光学系统响应矩阵的直接计算方法。通过分析特征驱动器斜率影响向量的实测值与理论值的相关性估计波前校正器与波前探测器的对准误差,得到了更接近实际情况的响应矩阵。实验结果表明,考虑对准误差后计算出的响应矩阵能够有效地进行闭环校正。Abstract: The interaction matrix of an adaptive optical system is directly computed. In this method, based on the correlation between the measured and theoretical slope influence vectors of the selected actuators, the misalignment between the wavefront sensor and wavefront corrector is first estimated, and then an interaction matrix more close to the real one is obtained. Experimental results show that with considering the misalignment, the interaction matrix acquired by direct computation becomes more effective in closed-loop correction, and the slope residual error is reduced.
