Optomechatronics design for mobile fringe patterns with applications on profilometry

In the next work an automatic fringe projection system with a mobile camera has been proposed. A set of experimental images in order to scanning all the set positions in an automated rail are obtained. In each position, four profileometric images shifted pi/2 were taken and use the phase shift of 4 steps algorithm to obtain the wrapped phase. A Radon transform analysis was applied to quantify the object move using the gray levels as scale. A qualitative process to analyze the profilometry of an object with an irregular surface is applied, getting good results.
