摘要

基于二氧化硅和聚合物(GOF和POF)的u型弯曲光纤传感器探头是低成本折射率(RI)传感器的理想选择。GOF昂贵、脆弱但稳定，而POF则是矛盾的。为了评估GOF和POF传感器探针在RI测量方面的相对优势和局限性，进行了详细的研究。使用内部开发的紧凑型手持式光纤折射仪进行实时监测，研究了RI传感器探头的测量重复性和温度稳定性。与GOF相比，POF探头的测量范围较宽，误差较大，温度稳定性较差。

Silica and polymeric fiber optic refractometric sensor probes: Performance evaluation

Silica and polymeric (GOF and POF) based U-bent fiber optic sensor probes are an excellent candidate for low-cost refractive index (RI) based sensors. GOF is expensive and fragile but stable, while POF is contradictory. To evaluate the relative advantages and limitations of the GOF and POF sensor probes with respect to RI measurements, a detailed study is carried out. Measurement reproducibility and temperature stability of the RI sensor probes were investigated using a compact, hand-held fiber-optic refractometer for real-time monitoring, developed in-house. POF probes show a wider measurement range with higher deviation and poorer temperature stability with respect to GOF.
