| 摘 要： | 分别对两种结构的传感头组成的分布式光纤Bragg光栅漏油传感器进行实验后得出，具有限位装置的传感头组成的传感系统综合性能好于由另一种结构传感头组成的传感系统。具有限位装置的传感头不仅有较好的漏油检测响应性能，而且能防止相邻信号间的串扰，同时能很好保护光纤光栅不被拉断，更重要的是它受温度干扰较小。

| Abstract: | Experiments of distributed fiber optic Bragg grating sensor for oil leakage detection, which is made respectively of two different sensing heads, are presented in this paper. Conclusions are drawn as follow: The integrative performance of the sensing system with the sensing head with the position-limiting setting is better than that of the other one. The former sensing system is not only of good performance of response for oil leakage, but also avoids interference between neighboring signals, besides protecting fiber optic grating from cracking. What is more important is that it suffers less affect of temperature. |
