利用声致发光成像技术测量液体中的声场

Real Time Measurement of Ultrosound Field Distribution in Liquid with Sonoluminescence Imaging Technology

利用自行改进的增强型ICCD成像系统记录水在超声作用下的声致发光图像,并且分析了声致发光的分布和强度与作用超声的关系,结果发现超声作用下的发光图像能够近似地反映该作用超声在水中的分布情况,从而提出了一种测量液体中超声场分布的新方法。该文从实验上证明了此方法的可行性。

In this paper, we recorded the image of sonoluminescence resulted from ultrasonic cavitation by the ICCD imaging system which was modified by ourselves. In the mean time, we analyzed the relation between the distribution and intensity of sonoluminescence and the ultrasound. The result showed that the sonoluminescence image could reflect the distribution of ultrasound in liquid. Consequently, a new method of measuring ultrasonic distribution was provided. In this paper, we validated the feasibility of this method by experiment.
