This paper describe the surface analysis based on the fringe projection technique. The grating of fringes is illuminated with plastic optical fiber multimode on a surface under test of the order of the cm2. This technique can be used to analyze the deformations of surfaces or errors of manufacture of objects when the projected fringes are compared with the original patterns generated by a computer program. The theoretical approach of the system has been made by means of the analysis of techniques of Moiré, being developed a method for the obtaining of parameters such as angles, phases and not known distances of the objects or surface under analysis. The preliminary experimental results and the potential applications appear. © 2008 American Institute of Physics.
