Abstract
Methods, systems and software for determining an optical surface model for an optical tissue system using Fourier transformation algorithms. A method of reconstructing optical tissues an eye comprises transmitting an image through the optical tissues of the eye. The surface gradients from the transmitted image are measured across the optical tissues of the eye. A Fourier transform algorithm is applied to the surface gradients to reconstruct an optical surface model that corresponds to the optical tissues of the eye.
