The relative positions and attitudes of the laser shadow system, the explosion chamber (optical window) and the high speed framing camera system were determined using a level bar and laser level. The axis of the metal wire is superposed with the left-right symmetrical line of the view field.

And step four, controlling the triggering time sequences of the high-speed framing camera 303, the laser 301 and the discharge trigger 111 through a delayer, setting triggering time delay according to theoretical prediction, and adjusting the triggering time delay to obtain a plasma evolution image at a typical moment of the collaborative explosion process.

Step ten, framing image data processing and analyzing:

and judging whether the energetic material can be detonated by the electric explosion, comparing the information between the two images obtained by framing, dividing the information by the time interval to obtain the expansion jet velocity of the metal wire and the expansion velocity of the energetic material, and giving a typical moment of the synergistic explosion process.
