摘要

建立了一种短腔长复合式光纤法布里-珀罗压力传感器反射光谱的模型,提出了一种双参数椭圆拟合腔长解调算法,并对腔长为26~30 μm的复合式法布里-珀罗腔的解调进行了仿真。结果表明,采用双参数椭圆拟合算法进行腔长解调的最大误差仅为0.05 μm。搭建了光纤法布里-珀罗传感器解调系统,在加压条件下对复合式光纤法布里-珀罗压力传感器进行了解调实验,实现了20 kHz的解调速率,验证了所提算法在解调短腔长复合式光纤法布里-珀罗压力传感器方面的可行性与实时性。

Abstract

A reflection spectrum model of a compound fiber-optic Fabry-Perot (FP) pressure sensor with short length is established, a two-parameter ellipse-fitting cavity length demodulation algorithm is proposed, and the demodulation for FP-cavity lengths in the range of 26-30 μm is simulated. The results show that the maximum error for the demodulated two-parameter ellipse-fitting cavity length is only 0.05 μm. A demodulation system for the fiber-optic FP sensor is established, and the experiments under different pressures are conducted. A 20-kHz demodulation rate is achieved. Thus, the feasibility and real-time performance of the proposed algorithm for demodulating a compound fiber-optic FP pressure sensor with a short cavity are verified.
