摘要: The measurement of human ocular aberration is now frequently performed because the increase in refractive surgery on cornea. Hartmann-Shack (H-S) wavefront sensor considered to be most useful sensor, and a calculation method for has been established. New methods measuring aberrations eyes, using Talbot image two-dimensional grating as local shift calculate tilt are shown. was determined by comparing phases fundamental spatial frequency between patch Fourier transformation. actual experiment modified commercially available analyzer. Using these methods, images were obtained from model eyes eye, shapes successfully reconstructed. Wavefront can measured even when degraded defocusing or scattering.
