摘要

二级级联AO (CAO)系统能够提高高对比度系外行星成像的波前校正。然而，进入第二阶段的第一阶段残差表现出拉锯式高频振荡。我们提出了一种补偿程序，将CAO变为低音-高音配置，从而显着提高整体性能。

Want to improve your cascade 2-stage AO system? Turn it into a high-performance woofer-tweeter!

2-stage cascade AO (CAO) systems enable to improve wavefront correction for high-contrast exoplanet imaging. However, 1st stage residuals entering the 2nd stage exhibit see-saw high-frequency oscillations. We propose a compensation procedure which turns the CAO into a woofer-tweeter configuration, thus significantly improving overall performance.
