Abstract

In this paper, a novel fiber-optic axial-strain sensor based on a micro-cavity Fabry-Perot interferometer (FPI) is proposed and experimentally realized. This micro-cavity FPI is mainly composed of a micro-air-bubble in a tapered hollow-core fiber fabricated by arc-discharged multiple-tapering technique. The experimental results show that the maximum sensitivity of axial-strain can reach ∼8.9 p.m./με in the range from 0 to 1100 με with high linearity. Additionally, high repeatability and ultra-low crosstalk of temperature (∼0.078 με/°C) are demonstrated, which brings a detection accuracy of 1.5 %. With the merits of compactness, low cost and ease of fabrication, the proposed sensor is very promising and potential to high precision axial-strain related measurement.

基于腔内微泡 fabry-perot 干涉仪的光纤轴向应变传感器

本文提出并在实验中实现了一种基于微腔法布里-珀罗干涉仪（FPI）的新型光纤轴向应变传感器。这种微腔法布里-珀罗干涉仪主要由锥形中空芯光纤中的微气泡组成，该光纤采用电弧放电多抽头技术制造。实验结果表明，在 0 至 1100 με 范围内，轴向应变的最大灵敏度可达 ∼ 8.9 p.m./με ，线性度高。此外，还具有高重复性和超低温度串扰（∼0.078 με/°C），从而使检测精度达到 1.5%。该传感器具有结构紧凑、成本低廉、易于制造等优点，在高精度轴向应变相关测量方面具有广阔的前景和潜力。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
