针对空间相机像差特点设计了校正低阶像差的9点促动变形反射镜，变形镜能够产生离焦、像散和彗差。对变形镜进行测试，结果表明变形镜在0.5 h间隔中的静态特性达到0.02λ（λ=632.8 nm），促动器控制面形的重复性精度达到0.01λ。采用4D干涉仪的Burst检测功能检测了变形镜的动态响应特性，其响应频率高于28Hz。应用变形镜为折叠镜，以空间相机为平台实验变形镜对离轴三反系统像差的校正。采用干涉仪和平面反射镜测量系统的波像差，采用系统像差响应构建变形镜响应函数，校正后系统波像差由0.122λ降低至0.0896λ，57.2 lp/mm空间频率处的系统传递函数由0.364提升至0.428。实验结果证明了变形镜能够有效地校正系统像差。

A 9-point active deformable mirror is designed according to the low order aberrations of space cameras, which can generate defocus, astigmatism and coma. The static and dynamic characters are tested. The testing results show that the static charater can reach 0.02λ(λ=632.8 nm) in several testing at 30 minutes time interval, and the repeatability accuracy is 0.01λ. The dynamic character is tested by the ‘Burst measure’ function of 4D interferometer. The response frequency is up to 28 Hz. The deformable mirror is applied to a space camera system as the fold mirror and the aberrations of the system are corrected. The testing results show that the root-mean-square (RMS) of wavefront is reduced from 0.122λ to 0.0896λ, and the modulation transfer function of system is improved from 0.364 to 0.428 at space frequency of 57.2 lp/mm. The test results verify the aberration correction ability of the deformable mirror.
