Methods, systems and software for determine an optical surface model for an optical tissue system using Fourier transformation algorithms. A method of reconstructing optical tissues of 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.
L'invention se rapporte à des méthodes, des systèmes et des logiciels permettant de déterminer un modèle de surface optique pour un système de tissus optiques en utilisant des algorithmes de transformée de Fourier. Elle concerne notamment une méthode de reconstruction des tissus optiques d'un oeil, consistant à transmettre une image à travers les tissus optiques de l'oeil, à mesurer les gradients de surface des images transmises sur l'ensemble des tissus optiques de l'oeil, et à appliquer un algorithme de transformée de Fourier à ces gradients de surface afin de reconstruire un modèle de surface optique correspondant aux tissus optiques de l'oeil.
