| Abstract: | Based on the principle of all-fiber single-mode velocity interferometer,a set of experiment equipment was assembled successfully,which was made up of single-mode fiber and coupler.In the experiment,the all-fiber single-mode velocity interferometer realized the measurement of high velocity with a deviation of 1.4% from a laser vibrometer.In the Hopkinson bar striking experiment,when the reference velocity is 20.86m/s,the measurement result is 20.57m/s.The feasibility of velocity interferometer is proved. |
