摘要：

The superposition of a parallel grating on a divergent grating will generate hyperbolic moiré fringes. Within this pattern of hyperbolic fringes one fringe, the limiting hyperbola, will be a straight line, and the position of this line can very effectively measure the separation of the parallel grating once the divergent grating has been calibrated. This method is used for measuring the spacing of Fizeau fringes.
