Abstract

A simple and automatic wavefront reconstruction is presented. This technique is based on the use of a plane computer display (a thin film transistor monitor) to generate the fringe patterns and compute the gradients field produced by the phase object. The accurate reconstruction is proved by the estimation of the surface map of a progressive ophthalmic lens, which is obtained using computational efficient techniques for the fringe pattern demodulation and gradient field integration.
