分析了双波前校正器全光路像差校正自适应光学系统的工作原理, 并通过共模波前传感器中的两套波前传感器探测得到的波前信息进行数据差分融合, 按照优化理论推导了两套波前校正器需要校正的像差公式。根据此像差公式, 仿真分析了以两套61单元变形反射镜组成的双波前校正器全光路像差校正自适应光学系统的校正能力, 并与单套波前校正器全光路像差校正自适应光学系统的校正能力进行了比较, 结果验证了推导的像差公式的正确性, 也说明了两套波前校正器不仅可以解耦, 而且其校正效果与理想行程单套波前校正器全光路像差校正自适应光学系统的校正效果相当。

The principle of an adaptive optics (AO) system with two sets of wavefront correctors for all-path aberration correction is analyzed. The measured wavefront information by two sets of Hartmann-Shack wavefront sensors is fused, and the optimized formula of the aberrations corrected by two sets of wavefront correctors is deduced. The performance of the AO system with two sets of wavefront correctors for all-path aberration correction is simulated. The result is compared with that of the AO system with a single corrector. The simulation result indicates the formula is right and the two sets of wavefront correctors can be decoupled. The correction performance is the same as that of AO system with a single deformable mirror with ideal stroke.
