摘要
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 。
The correction method of two adaptive optics (AO) systems in series was put forward. An AO system with feed forward control loop was connected to an AO system with feed back control loop by a community wave front corrector. The control performance and the transfer characteristics of noise by this method were analyzed. This method is not much more complex technically than normal method of single AO system, but the control performance of the two systems in series is improved greatly in comparison with that of single AO system. The simulation results with experimental data on the 61-element AO system verify the availability of this method.
