| 摘 要： | 用有限元分析获得了环扇形分块主镜的镜面热变形数据,分别用圆域Zernike多项式和环扇域Zernike多项式对其进行了波面拟合,比较了用两种多项式的拟合精度。基于哈特曼-夏克波前传感器对由环扇形镜面热变形引起的畸变波前进行了模式法重构,分析了用上述两种多项式重构时矩阵条件数和测量误差对重构精度的影响。

| Abstract: | Using finite element analysis,thermal deformation data of annulus-sector segmented primary mirror are obtained.Zernike circular polynomials and Zernike annulus-sector polynomials are used to fit the discrete date respectively.Then the fitting precision is compared.Based on Hartmann-Shark wavefront sensor,modal wavefront reconstruction of distorted wavefront induced by thermal deformation mirror is realized.Using two different polynomials before-mentioned,influences of the condition number and measurement error on reconstruction precision are discussed. |
