针对三种不同空间分辨率的双压电片变形镜(Bimorph DM)，采用仿真实验分析其对3~35 项Zernike 静态像差和实际人眼(包括疾病人眼)像差的拟合能力。实验表明，Bimorph 变形镜特别适用于校正低阶像差，拟合误差小于0.15，随着空间分辨率的增加，Bimorph 变形镜对Zernike 像差和人眼像差的拟合能力总体表现为增强的趋势，其中，35 单元的Bimorph 变形镜的像差拟合能力最优，对前20 项Zernike 像差的拟合误差稍优于传统分立式压电变形镜。通过对Bimorph 变形镜像差拟合能力的实验分析，为人眼视网膜高分辨率系统的Bimorph 变形镜选型提供了分析方法，也为进一步提升Bimorph 变形镜的像差校正能力奠定了研究基础。

This study adapted simulations to analyze the fitting capabilities to human aberration of three kinds of Bimorph Deformable Mirrors (DMs) with different spatial resolutions, especially the capability to fit to 3~ 35th orders of Zernike static aberrations and the human aberrations, including the eye of diseases. It’s shown that Bimorph DM is well suitable for fitting to low-order aberrations with the error less than 0.15. As the spatial resolution increased, the capability of fitting aberrations enhanced totally. Compared with traditional discrete piezoelectric DM, 35-element Bimorph DM had smaller fitting error on the first 20th Zernike aberration. This simulated analysis provided an analytical method for the selection of Bimorph DMs for high-resolution human eye imaging systems. In addition, it provided a research foundation of further improvement of the Bimorph DM in fitting aberrations capability.
