  • To overcome the limitation of fringe counting and phase analysis,a new method based on the time-frequency analysis is proposed to process the self-mixing interference signal.The frequency of the self-mixing interference signal is acquired by time-frequency analysis,and this frequency is equal to the Doppler shift,so the velocity of external object is gained easily.The simulation experiments show that the proposed method is very easy,effective,and accurate.
