F-P腔传感器灵敏度的仿真与分析

Simulation and analysis on sensitivity of F-P sensor

搭建了光纤超声波传感器解调系统,检测并解调出39.4k Hz超声波场的时域和频域信号。分别研究了不同频率特性、不同膜片厚度和不同检测角度下F-P传感器对局放信号测量的影响。

This paper built the demodulation system for fiber ultrasonic sensor, the time and frequency domain signal of the 39.4kHz ultrasonic field is detected and solved. It studied the influence of F-P sensors for partial discharge signal measurement with different frequency characteristics, diaphragm thickness and detection angle.
