Abstract

A method for detecting changes in the length of an optical cavity is proposed for fiber-optic sensors based on the Fabry–Perot interferometer scheme. The possibility of detecting oscillations of the resonator length at the subnanometer level in the frequency band 1.5–300 kHz is shown. The sensitivity was 0.3 nm in standard deviation. The proposed scheme makes it possible to reliably distinguish high-frequency oscillations against the background of slow drifts of the sensor length caused by temperature fluctuations or deformations.

利用跟踪串联低相干干涉仪检测光纤传感器中纳米长度振荡的方法

基于法布里-珀罗干涉仪方案，为光纤传感器提出了一种检测光腔长度变化的方法。结果表明，在 1.5-300 kHz 的频段内，可以检测到亚纳米级的谐振器长度振荡。灵敏度的标准偏差为 0.3 nm。在温度波动或变形导致传感器长度缓慢漂移的背景下，所提出的方案能够可靠地分辨出高频振荡。
