  • In the present study, to directly measure the radial strain of a metal sample loaded by the split Hopkinson pressure bar (SHPB) facility, we developed a new all-fiber displacement interferometer that could output signals of invariable strength by adopting a semiconductor optical amplifier (SOA) followed by an erbium doped fiber amplifier (EDFA) to control the light intensity reflected from the measured sample during the dynamic measurement process.The theoretical study showed that the displacement measurement resolution was free from the fluctuation of the output intensity, and the experimental results demonstrated that this new interferometer could measure the elastic and plastic strains of metal sample loaded by the SHPB with high resolution.
