Abstract

Metodos, sistemas y software para determinar un modelo de superficie optica para un sistema de tejido optico utilizando algoritmos de transformacion Fourier. Un metodo para reconstruir tejidos del ojo comprende transmitir una imagen a traves de los tejidos opticos del ojo. Los gradientes de superficie de la imagen transmitida se miden a traves de los tejidos opticos del ojo. Se aplica un algoritmo de transformacion Fourier a los gradientes de superficie para reconstruir un modelo de superficie optica que corresponde a los tejidos opticos del ojo.
