High-speed photography for electrical explosive loaded multi-layer target

High-speed photography applied in electrical explosive loaded multi-layer aluminum target is described. The moving fragment images and ejection of material produced by striking Mylar film on two-or-three-layer aluminum target was obtained with high-speed photography and laser shadowgraph in various conditions, such as different voltages of explosive bridge, thicknesses and spaces between aluminum plates. The speed of the fragments and the micro surge were acquired in the experiment.
