谢谢指正,这几天也在看zernike多项式这一块,被资料中的一句话误导了“An alternate ordering of the terms was formulated in the 1970s, which permits better fitting of the type of zonal errors that are commonly encountered when fabricating large aspheric optical components. For historical reasons, this set of polynomials is referred to as the Extended Fringe Zernike polynomials. Both of these sets of polynomials can have any number of terms” ,就觉得zernike是为非球面而创造。但看了五楼的多项式表达式,主要还是自由曲面的形式,表达式中包含θ的项都属于非旋转对称的自由曲面项,不光光是Z3与Z4这两项。
