The jet was supplied with tiny water droplets, produced by condensation, which caused scattering of laser light illuminating the section of the jet in meridian plane. A high-speed camera, operating in an adjustable phase relationship with acoustic signals triggering the formation of the instabilities was used to record the visualisation images. These were then processed using advanced procedures aimed at identifying the structures.
