It is desirable in the moire method that fringe patterns with narrow fringe widths be obtained in order that the experimental accuracy may be raised. For this purpose special grids with different widths of bright and dark regions are useful. In this paper, new equations for determining simply the fringe widths formed by the grids with large pitches are proposed considering the widths of grid lines. These new equations are applied to several cases of special grids, and it is confirmed that new equations are valid experimentally. Besides, new fringes (false-bright fringes) are found to exist, and the nature of these fringes is examined.
