  1. 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的zernike多項式的性質;針對主觀式像差儀前斜率采樣方案,提出了採用帶標準化因的zernike多項式對眼測試前進行重建的數學模型;提出了兩種求解方法,即基於householder求解法和基於gram - schmidt化求解法,用於確定重建模型中的未知模式系數;推導出了該前重建模型對斜率測量誤差的傳遞系數。
