When testing the surface figure of large aperture optical components, phase noise of light source used in the phase shifting interferometer will influence the test precision. However, it is not easy to analyze the random phase noise directly. In order to have an understanding of phase noise, an experiment is designed to get beat frequency from two separate lasers. The possibility of obtaining phase noise from beat frequency is discussed. It is a good foundation for the improvement of the large aperture optical test system.
