　　Since the noise affects the quality of the Fizeaus interferograms in the large aperture,the rotated diffuser was driven by the motor to reduce the noise.The relationships between the frequency of the rotated diffuser,the contrast of the fringes and the SNR of the system were simulated.Then,the appropriate parameters were selected.The experiment was carried out by placing the rotated diffuser in Fizeau interference system of a large aperture,the results were similar with the simulations.
