Characterization of shock waveform at focal plane perpendicular to the beam axis, using a fiber optic hydrophone (RP Acoustics FOPH 500): (a) A schematic drawing showing the distribution of 41 locations where pressure time-history is measured. (b) The pressure waveform measured at the focal point. (c) Variation of peak pressure along the y-axis, with error bars. (d) Variation of peak pressure along the z-axis, with error bars.
