Paper Abstract

This paper reports the moire technique by means of electronic XOR logic for obtaining 3-D object contour moire fringes in real time. The main advantage of this method is removal of carrier frequency noise. In this method, the rotation of equiorder surfaces is obtained by changing the period of projection grating. Also, the slope contour fringes are obtained by moving the object in lateral. The projection system is used by means of a self-imaging Talbot effect. The details of equations and the experimental results are presented.
