摘要
Systems, methods, and devices for determining an optical surface model for anoptical tissue system of an eye are provided. Techniques include inputting aFourier transform of optical data from the optical tissue system, inputting aconjugate Fourier transform of a basis function surface, determining a Fourierdomain sum of the Fourier transform and the conjugate Fourier transform,calculating an estimated basis function coefficient based on the Fourierdomain sum, and determining the optical surface model based on the estimatedbasis function coefficient. The approach is well suited for employing Fouriertransform in wavefront reconstruction using Zernike representation.
