摘要 变形镜能够实时校正波前相位畸变,减弱大气湍流的影响,是自适应光学系统的核心器件。单驱动器变形镜通过1个驱动器产生1个模式,恢复波前相位。利用有限元软件,研究了单驱动器变形镜对低阶像差的补偿能力。仿真结果表明,单驱动器变形镜可以对离焦、像散及彗差进行有效补偿,通过控制驱动器的位移,分别实现了对PV值为5μm的离焦、像散和慧差的补偿,补偿后的残差PV值分别为1.5μm、1.6μm和1.2μm,残差的RMS值分别为0.99μm、0.63μm和0.59μm。 The wave front phase aberrations can be corrected by deformable mirror in real time,which is the key element of adaptive optics system for reducing the effect of atmospheric turbulence.The wave front error can be compensated by deformable mirror with single actuator:one optical mode is generated with one actuator.Finite element analysis was employed to research the compensation capacity for the low order aberration of single actuator deformable mirror.The simulation results show that the wave front error of defocus,astigmatism and coma can be effectively corrected using single actuator deformable mirror by controlling the displacement of actuator.The peak valley(PV)values of fitting errors of defocus,astigmatism and coma are 1.5μm,1.6μm and 1.2μm,respectively,comparing to the initial PV value of 5μm.The root-mean-square(RMS)values of fitting errors are 0.99μm,0.63μm and 0.59μm,respectively.
