Abstract

A fiber Bragg grating (FBG) voltage sensing system based on an optoelectronic oscillator (OEO) with the Vernier effect is proposed. The system can convert the FBG wavelength shift into the frequency shift of the OEO output microwave signal by introducing dispersion within the loop. Since the wavelength of the FBG varies with voltage by bonding FBG to piezoelectric ceramic (PZT), the system can measure voltage by monitoring the frequency shift of the OEO. Two FBGs are placed inside the loop to form a dual-loop structure. By controlling the length difference between the two loops, the Vernier effect can be realized and the sensitivity of the voltage sensing system is improved. Meanwhile, due to the similar temperature-sensitive performance of the two FBGs, the system can realize temperature compensation to reduce the temperature-induced voltage measurement error. The sensitivity of the voltage sensing system based on the single-loop OEO is 367.25 Hz/V, while the sensitivity of the voltage sensing system based on the dual-loop OEO is 93.07 kHz/V, which is 253 times higher than that of the single-loop voltage sensing system. The temperature sensitivity of the voltage sensing system is measured to be 46.64 kHz/°C. A high-resolution voltage sensing system based on an OEO with the Vernier effect is realized.

基于游标效应光电振荡器的高分辨率光纤光栅电压传感系统

提出了一种基于游标效应的光电子振荡器（OEO）的光纤布拉格光栅电压传感系统。该系统通过在环路内引入色散，将光纤光栅的波长位移转化为OEO输出微波信号的频移。由于光纤光栅与压电陶瓷（PZT）相结合，光纤光栅的波长随电压变化，因此该系统可以通过监测压电陶瓷的频移来测量电压。在环路内放置两个fbg，形成双环路结构。通过控制两回路之间的长度差，实现了游标效应，提高了电压传感系统的灵敏度。同时，由于两种fbg具有相似的温度敏感性能，该系统可以实现温度补偿，以减小温度感应电压测量误差。基于单环OEO的电压传感系统灵敏度为367.25 Hz/V，而基于双环OEO的电压传感系统灵敏度为93.07 kHz/V，是单环电压传感系统灵敏度的253倍。该电压传感系统的温度灵敏度为46.64 kHz/°C。实现了一种基于游标效应OEO的高分辨率电压传感系统。
