According to the geometry of slope measurements for the subjective wavefront optometer , a wavefont reconstruction model using zernike polynomial with normalization factor is put forward . based on householder transformation and gram - schmidt orthogonalization method , two methods for working out unknown zernike coefficients are bring forward . the error propagation parameter for the wavefront reconstruction model is deduced 深入研究了帶標準化因子的zernike多項式的性質;針對主觀式像差儀波前斜率采樣方案,提出了采用帶標準化因子的zernike多項式對眼測試波前進行重建的數學模型;提出了兩種求解方法,即基于householder變換求解法和基于gram - schmidt正交化求解法,用于確定重建模型中的未知模式系數;推導出了該波前重建模型對斜率測量誤差的傳遞系數。
