针对目前超声空化强度检测存在的实时性差、难以实现在线监测、稳定性差、难以定量检测等问题,提出了一种基于单光子探测的超声空化强度检测方法。介绍和推导了该检测方法的基本原理,根据该原理构建了超声空化强度检测装置,并通过实验验证了超声空化强度与90度Mie散射光的光子计数值之间成线性关系。该方法弥补了现有检测方法的不足,为进一步更加准确地测量超声空化强度创造了有利的条件。
Aiming at the problems such as poor real-time performance of ultrasonic cavitation detection, difficulty of on-line monitoring, poor stability and difficult quantitative detection, an ultrasonic cavitation intensity detection method based on single-photon detection is proposed. The basic principle of this method is introduced and deduced. Based on this principle, an ultrasonic cavitation intensity detection device is constructed and the linear relationship between the ultrasonic cavitation intensity and the photon count value of 90 ° Mie scattering light is verified by experiments. The method can make up for the deficiency of the existing detection methods and create favorable conditions for further more accurately measuring the ultrasonic cavitation intensity.
