Cavitation events are short-lived gas bubbles that occur under the correct physical conditions. In order to study these events high- speed cameras can be used to understand the dynamics of the interfaces involved and the effects they have of other sensors placed close to them. In this project two camera systems will be developed with the ability to acquire images at high rates (up to 400,000 frames per second). Under these conditions the cavitation events can be viewed in real time and their effects correlated with the data obtained from a number of different sensors placed within the local environment. These sensors will use, for example, electrochemical and acoustic technology to detect how the liquid around the bubble moves and the damage that the bubbles can do to a solid surface. This study will enable the true effects of cavitation, and related bubble phenomena, to be clarified. In addition these camera systems will be used to study the fast motion of aquatic organisms (for example the mantis shrimp) which are suspected to generate large cavitation bubbles as they attack their prey/defend themselves from other predators. Finally the cameras will be used to study the processes that occur at the gas/liquid interface of a breaking wave.

空化事件是在正确的物理条件下发生的短暂气泡。为了研究这些事件，高速摄像机可以用来了解所涉及的界面的动态以及它们对靠近它们放置的其他传感器的影响。在该项目中，将开发两个能够以高速率（高达每秒400，000帧）获取图像的相机系统。在这些条件下，可以在真实的时间内观察空化事件，并且它们的影响与从放置在局部环境内的多个不同传感器获得的数据相关。例如，这些传感器将使用电化学和声学技术来检测气泡周围的液体如何移动以及气泡对固体表面造成的损害。这项研究将使气穴的真实影响以及相关的气泡现象得到澄清。此外，这些相机系统将用于研究水生生物（例如螳螂虾）的快速运动，这些水生生物被怀疑在攻击猎物/保护自己免受其他捕食者的攻击时会产生大的空化气泡。最后，相机将被用来研究发生在气/液界面的破碎波的过程。
