The optical intensity distribution of a generalized two-grating interferometer is derived in this paper. The influence of ratio of grating period to slit width on Lau fringesis analyzed. We show that the clear Lau fringes for β>p/(2a) do exist and their existe-nce is verified by experiment and numerical calculations.
