Paper Abstract

For the investigation of the dynamics of tiny, fast moving cavitation bubbles we devel-oped high speed holocinematographical recording techniques. In most experiments we used a multiply Q-switched ruby laser as illuminating light source. The maximum number of holograms which could be recorded in one sequence was limited to eight in this case. More recently, we examined the cavity-dumped argon ion laser for recording longer hologram series. The experimental devices operate in the range of 10 000 to 20 000 holograms per second with ruby laser illumination and at pulse rates up to two kilohertz with argon ion laser illumination. For separating successively recorded information we employed spatial multiplexing techniques in both cases. Reconstructed hologram series taken of acoustically produced cavitation bubbles demonstrate the performance of the experimental arrangements. From the recordings bubble motion can easily be evaluated.
