文中作者推导出了两块相同角栅距的圆光栅配对时产生莫尔条纹的轨迹方程。接着又介绍圆光栅产生“直形”莫尔条纹和圆环形莫尔条纹的条件。最后,提出了莫尔条纹宽度的分布规律。
In this paper, the authors derive the trajectory equation of the moire fringe when two circular gratings with the same angular pitch are paired. Then introduced the circular grating produce “straight” moire fringes and ring moiré conditions. Finally, the distribution rule of Moiré fringes is proposed.
