Monitoring system for measuring air local disturbance position based on tuning fork resonance

A monitoring system for measuring an air local disturbance position based on tuning fork resonance comprises a plurality of monitoring units, each monitoring unit comprises a laser, a high-reflectivity mirror, a photosensitive screen and a high-speed CCD, the number of the high-reflectivity mirrors is three, a tuning fork is arranged on the high-reflectivity mirror where the laser firstly emits light, then the light is sequentially reflected to the remaining high-reflectivity mirrors, and the high-speed CCD is connected with the photosensitive screen. According to the invention, the vibration signal of the vibration source in the air can be monitored more sensitively, the position of the vibration source, including the direction and the distance, can be quantitatively judged, and the response frequency range is wider. 一种基于音叉共振来测量空气局部扰动位置的监测系统，包括多个监测单元，所述监测单元包括激光器、高反镜、感光屏幕以及高速CCD，所述高反镜设置有三个，其中激光器最先射入的高反镜上具有音叉，随后依次反射到剩余的高反镜上，并照射到感光屏幕上，高速CCD设置在感光屏幕一侧对激光位置进行追踪，本发明能更灵敏的监测空气中震动源的震动信号，可以定量判断震源位置，包括方向和距离，响应频率范围更广。
