提出了一种用两个自适应光学系统串联校正的方法。这两个自适应光学系统分别采用前馈控制和反馈控制布局 ,利用一组共用的波前校正器串联起来。分析了这种串联校正方法的控制性能和噪声传递特性 ,在技术复杂性增加不多的条件下 ,这种串联结构的整体控制效果比单一系统改善了很多。用实际 6 1单元自适应光学系统上的实验数据进行了仿真 ,验证了这种方法的有效性
A method of series correction using two adaptive optics systems is proposed. The two adaptive optics systems use feedforward control and feedback control layout, respectively, in series with a common set of wavefront correctors. The control performance and the noise transfer characteristic of this series correction method are analyzed. The overall control effect of this series structure is much better than that of the single system under the condition that the technical complexity increases little. The experimental data on an actual 6 1-unit adaptive optics system were used to simulate the effectiveness of this method
