We have evaluated the ability of three commercially available deformable mirrors to compensate the aberrations of the eye using a model for aberrations developed by Thibos, Bradley and Hong. The mirrors evaluated were a 37 actuator membrane mirror and 19 actuator piezo mirror (OKO Technologies) and a 35 actuator bimorph mirror (AOptix Inc). For each mirror, Zernike polynomials and typical ocular aberrated wavefronts were fitted with the mirror modes measured using a Twyman-Green interferometer. The bimorph mirror showed the lowest root mean square error, although the 19 actuator piezo device showed promise if extended to more actuators. The methodology can be used to evaluate new deformable mirrors as they become available.
我们使用由蒂博斯、布拉德利和洪开发的像差模型，评估了三种市售可变形镜补偿眼睛像差的能力。所评估的镜子分别是一个37个驱动器的薄膜镜、一个19个驱动器的压电镜（OKO技术公司）和一个35个驱动器的双压电晶片镜（AOptix公司）。对于每面镜子，使用泰曼-格林干涉仪测量镜子模式，并将泽尼克多项式和典型的眼部像差波前与之拟合。双压电晶片镜的均方根误差最低，不过19个驱动器的压电器件如果增加驱动器数量，有望表现更好。该方法可用于评估新出现的可变形镜。
