We demonstrate an interferometric method to provide direct, single-shot measurements of cavitation bubble dynamics with nanoscale spatial and temporal resolution with results that closely match theoretical predictions. Implementation of this method reduces the need for expensive and complex ultra-high speed camera systems for the measurement of single cavitation events. This method can capture dynamics over large time intervals with sub-nanosecond temporal resolution and spatial precision surpassing the optical diffraction limit. We expect this method to have broad utility for examination of cavitation bubble dynamics, as well as for metrology applications such as optorheological materials characterization. This method provides an accurate approach for precise measurement of cavitation bubble dynamics suitable for metrology applications such as optorheological materials characterization.
我们展示了一种干涉测量方法，可对空化气泡动力学进行直接的单次测量，具有纳米级的空间和时间分辨率，其结果与理论预测紧密匹配。该方法的实施减少了对用于测量单个空化事件的昂贵且复杂的超高速相机系统的需求。此方法能够以亚纳秒级的时间分辨率和超越光学衍射极限的空间精度，在大时间间隔内捕捉动力学过程。我们预计该方法在空化气泡动力学研究以及诸如光流变材料表征等计量应用中具有广泛的用途。该方法为精确测量空化气泡动力学提供了一种准确的途径，适用于诸如光流变材料表征等计量应用。
