New methods of measuring aberrations of human eyes, using the Talbot effect of a 2-dimensional grating as a wavefront sensor and Fourier transform for calculating tilt of the wavefront, are shown. Using these methods, wavefront aberrations can be measured even when the obtained image is degraded by the scattering.
