Abstract

The present invention provides methods, systems and software for generating a wavefront elevation map using Fourier transformation algorithms. In one embodiment, the present invention provides a method of reconstructing optical tissues of an eye. The method 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 a surface that corresponds to the optical tissues of the eye.
