Abstract

On-line fabricated fiber Bragg grating (FBG) array and its sensing potentials have attracted plenty of attention in recent years. In this paper, FBG arrays are written on-line on a two-mode fiber, and this two-mode fiber Bragg grating (TM-FBG) is further experimentally investigated for temperature and curvature sensing. The responses of this sensor were characterized by 11.2 pm/°C and -0.21 dB/m for temperature and curvature, respectively. Based on the measurements, a dual-parameter fiber sensing system was developed, which can realize the quasi-distributed, simultaneous detection of temperature and curvature, making it suitable for structural health monitoring or perimeter security.

摘要

近年来，在线制作的光纤布拉格光栅（FBG）阵列及其传感潜力引起了广泛关注。本文中，FBG阵列在双模光纤上在线写入，并对这种双模光纤布拉格光栅（TM-FBG）进行了温度和曲率传感的进一步实验研究。该传感器对温度和曲率的响应分别为11.2 pm/°C和-0.21 dB/m。基于这些测量结果，开发了一种双参数光纤传感系统，该系统可以实现温度和曲率的准分布式、同时检测，使其适用于结构健康监测或周界安全防护。
