Acoustically induced cavitation at 20 kHz is observed by means of
high speed video recording.
Using digital image processing the bubbles' trajectories are investigated.
The data reveals a
complicated near field interaction between the bubbles.
A dominant phenomenon is the collision and
coalescence of bubbles, even in the relatively sparse populated streamers.
