表面介质阻挡放电控制气流的空气动力学研究一直是人们关注的焦点。要理解该机制，需要考虑的一个重要因素是压力波，压力波包括从表面电介质阻挡放电发射的声波和冲击波。在本文中，光纤光波麦克风，它改善了传统的光波麦克风的信噪比方面，开发了高精度检测这些压力波。本文探讨了光纤式光波传声器的特性。一个高速相机被用来捕捉时间分辨的微放电。同时观察了表面介质阻挡放电的电压、电流、压力波和微放电图像，分析和讨论了这些因素之间的关系。
Much focus has been placed on the aerodynamics of surface-dielectric-barrier discharges to control air flow. An important factor to consider to understand the mechanism is pressure waves, which include acoustic waves and shock waves that are emitted from the surface-dielectric-barrier discharges. In this paper, a fibered optical wave microphone, which improves upon a conventional optical wave microphone with regard to signal-to-noise ratio, was developed to detect these pressure waves with high precision. This paper explores the properties of the fibered optical wave microphone. A high-speed camera was used to capture time-resolved microdischarges. After simultaneous observation of the applied voltage, current, pressure waves, and microdischarge images for the surface-dielectric-barrier discharge, the relationships among these factors were analyzed and discussed.
