Abstract
The standard fringe projection technique requires a non-zero angle between projection and observation directions to have sensitivity in the z direction. In this work, a new method is presented where the angle between projection and observation directions is zero, but the system presents sensitivity due to divergent projection which changes the fringes frequency in each one of the normal planes to z-axis. The experimental results compared with the standard fringe projection technique are presented in this work to show the accuracy of the method proposed.
