For a reliable judgement of the erosive aggressiveness of cavitation close inspection of cavitation implosions are necessary. The conventional time lapse method cannot accurately detect the temporal development of cavitation. A better method is to use high-speed video combined with simultaneous high-frequency measurement of huil pressure signals. This paper discusses both observation methods and a newly developed high-speed observation system for depressurised towing tanks and full scale observations. Furthermore, the first high-speed recordings obtained on model scale and on full scale are presented.
