摘要
Wavefront measurements of eyes are normally taken when the pupil is relatively large, and the results are often represented by a set of Zernike coefficients. Different sets of Zernike coefficients can be calculated to represent aberrations at smaller pupil sizes. While recently described techniques allow scaling of the expansion coefficients with Zernike polynomials, a more intuitive approach would be desirable. Such an approach may optionally derive an equivalent result as known techniques, but may employ a much simpler and nonrecursive formula between the new and the original sets of Zernike polynomial expansion coefficients of a wavefront when the aperture size is scaled.
