Wave aberrations in the human eye are usually known with respect to the ideal spherical wavefront in the exit pupil. Using Kirchhoff's diffraction theory, we have derived a diffraction integral to compute the optical field on the retina from the wave aberration data. We have proposed a numerical algorithm based on the Stamnes-Spjelkavik-Pedersen (SSP) method to solve that integral. We have shown which approximations are admissible to reduce the complexity of the diffraction integral. In addition, we have compared our results with those of the conventional procedure used to compute intensities on the retina. We have found significant differences between our results and the conventional ones.
人眼的波像差通常是相对于出瞳中的理想球面波前而言的。利用基尔霍夫衍射理论，我们推导了一个衍射积分，以便根据波像差数据计算视网膜上的光场。我们提出了一种基于斯坦内斯 - 斯皮尔克维卡夫 - 佩德森（SSP）方法的数值算法来求解该积分。我们已经表明哪些近似是可行的，以降低衍射积分的复杂性。此外，我们将我们的结果与用于计算视网膜上强度的传统方法的结果进行了比较。我们发现我们的结果与传统结果之间存在显著差异。
