In this paper,we use a fiber mode coupling method to analyse a fiber optical velocity interferometer system for any reflector and use it to measure low velocity impact specimens with diffuse reflecting surface. The experiment results agree with theoritcal analysises fairly and the profile of velocity vs time is first obtained in the experiment.
