Adaptive optics systems are powerful tools that are implemented to degrade the effects of wavefront aberrations. In this article, the optimal actuator placement problem is addressed for the improvement of disturbance attenuation capability of adaptive optics systems due to the fact that actuator placement is directly related to the enhancement of system performance. For this purpose, the linear-quadratic cost function is chosen, so that optimized actuator layouts can be specialized according to the type of wavefront aberrations. It is then considered as a convex optimization problem, and the cost function is formulated for the disturbance attenuation case. The success of the presented method is demonstrated by simulation results.

自适应光学系统是强大的工具，用于降低波前像差的影响。在本文中，由于执行器放置与系统性能的增强直接相关，因此解决了最佳执行器放置问题以提高自适应光学系统的干扰衰减能力。为此，选择线性二次成本函数，以便可以根据波前像差的类型专门优化致动器布局。然后将其视为凸优化问题，并为干扰衰减情况制定成本函数。仿真结果证明了所提出方法的成功。
