  • 摘要: 限制自适应光学(Adaptive Optics, AO)系统表现的一个关键因素是由波前传感器所在路径和科学成像路径之间差异引起的非共光路像差(Non-Common Path Aberration,NCPA),同时AO系统共光路部分也会不可避免地引入静态像差。为此,本文提出了一种基于焦面点扩散函数(Point Spread Function,PSF)复制的技术,用于校正AO系统中的静态像差。此技术利用点光源产生的PSF图像作为参考图像,通过迭代优化算法控制可变形镜改变其面型,将参考PSF图像复制到AO系统科学成像路径。实验结果表明,校正后的斯特列尔比(Strehl Ratio,SR)从初始的0.312提高到0.995。此技术可以稳定、快速地获得全局校正结果,特别是在系统具有较大的初始静态像差时。
