Results of a 14 gauge front cut model needle shot inside deionized water. (a) Images from the high speed video (Supplementary Video 2, total frame size 9.6 mm \(\times\) 7.2 mm). (b) Spectrogram of the acoustic emission. (c) Time interval of interest from (d), which shows the vertical displacement of the needle along the z axis (expected uncertainty \(\pm 25\) µm, one pixel), plotted with the projected area of cavitation bubbles as a function of time. Note that plots (b,d) share the same time axis and the numbered dashed lines in (c) refer to the indices of the images in (a).
