Abstract: The arriving time of the metal flyer at some point was measured by two kinds of combined probes for checking their uniformity. Meanwhile, the free-surface velocity and displacement of the metal flyer were measured by double-sensitive VISAR for contrast with combined probes. Experiment results show that the first stage probe of the vertical combined probe coincides well with the horizontal combined probe; the second stage probe has a little difference with the horizontal combined probe; the difference increases along with the stage of vertical combined probe, and the reason is the interference of the probe on the flyer. The maximum differences at the measuring point 1 between two kinds of combination probes and VISAR are 0.71% and 0.67% respectively, and the maximum differences at point 2 are 0.98% and 0.90% respectively. Two kinds of combined probes can be used together to acquire more data in the experiments.
