我们展示了一种干涉方法，提供直接的，单次测量的空泡动力学与纳米级的空间和时间分辨率与结果密切匹配的理论预测。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要。这种方法可以捕捉动态在大的时间间隔，亚纳秒的时间分辨率和空间精度超过光学衍射极限。我们希望这种方法具有广泛的实用性，检查空化气泡动力学以及计量应用，如光流变材料表征。该方法提供了一种精确的方法，用于精确测量空化泡动力学的计量应用，如光流变材料表征。
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.
