Outline
A transverse velocity interferometer system for any reflector (VISAR) has been developed by combination of a multipoint VISAR and a tri-probe device. One probe emits and receives laser, and the other two probes receive laser from different directions. The transverse and longitudinal velocities can be deduced from Doppler shift of laser received by the tri-probe. The transverse VISAR were applied to detonation driving wedge target experiments. Planar shock wave in a 10° wedge steel target was generated by plane-wave lens and T/Γ explosive. The free surface transverse velocities induced by oblique collision of shock wave were measured. The maximum measured longitudinal velocity is about 1 680 m/s, and the maximum measured transverse velocity is about 140 m/s. The uncertainty of the transverse velocity measurement was analyzed, and the uncertainty is estimated to be about 33 m/s in the experiments.
