This paper reports the Moire technique by means of digital electronic XOR logic for obtaining 3-D object contour fringes in real time. The main advantage of this method is removal of the unwanted patterns. In this method the rotation of equlorder surfaces is obtained by changing period of projection grating. Also the slope contour fringes are obtained by moving the object in lateral. The projection system by means of self-imaging Talbot effect is used. The experimental results are presented.
