Canging Law of Moire Fringe

In this paper, the productive reason of moire fringehas been introduced, and the relations among the space length ofmoire fringe in one dimension situation, the direction and thedistance of the two gratings. the included angle of the tracks, theopposite position of the tracks, the space length of the twogratings, the position of observer's eyes have been pointed out.Then the changing laws of moire fringe are introduced, and thecaculation formula of equivalent grating distance is given. Theapplied field of moire fringe are indicated also.
