Abstract
A method is proposed to solve one of the problems that profilometry encounters when fringe projection techniques are used: the difficulty to discern between surface discontinuities that cause phase shifts greater than 2π. Based on fringe projection of a single composite fringe pattern containing three different frequencies, such problem can be solved. Experimental results are presented using Fourier methods.
