Study of electronic XOR logic Moire technique and effect of differential equiorder surfaces rotation
摘要
本文提出利用数字电子XOR(异或)运算,得到三维物体的实时等高线条纹,这种莫尔技术的特点是能消除莫尔纹的载频.用该方法,通过改变投影光栅周期,实现空间等高剖面的旋转,横向移动物体得到实时的斜率等位线条纹,并给出实验结果.
Abstract
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.
