Bubble Collapse Studies at a Million Frames per Second

摘要: The phenomenon of laser-induced breakdown in liquids, for a long time just investigated its own sake [1–4] has been applied several years to the longstanding problem cavitation bubble dynamics [5–9]. High speed hotographic [5–8] and holographic methods [9] have employed. However, ince cavities occurring upon proved o be never exactly repeatable size cavity after breakdown, as .g. first collapse, could not studied systematically with high esolution. This can now achieved by sophistication experimental set-up which we report here. essential idea is that avity itself used trigger photographic equipment via he modulation He-Ne laser light beam.
