The plasma produced by the electrical explosion of a metal array bridge foil converges, which helps improve the energy utilization efficiency in the process of electrical explosion. Atomic emission spectrometry was carried out to conduct a spatiotemporal analysis of the plasma spectrum produced by the electrical explosion of array and single bridge foils, and the influence of the structure of the bridge foils on the spectral intensity of the plasma was analyzed. The Boltzmann multispectral slope method and the Stark broadening method were applied to obtain the evolution laws of the temperature and electron density of the plasma over time. The results show that compared with the single bridge foil, due to the convergence effect of the plasma, the spectral intensity and temperature of the plasma generated by the electrical explosion of array bridge foils are higher in the convergent zone, while the electron density is lower.
