Abstract

The first results are presented that demonstrate the applicability of a coherent optical frequency-domain reflectometer based on a self-sweeping fiber laser for sensing. An array of various fiber Bragg gratings (FBGs) was used as the sensing line. It is shown that FBGs with a reflection spectrum that lies outside the scan region of ​​our source can be used in the developed reflectometer. Using the frequency-domain reflectometry technique, it is possible to perform spatial separation of FBG sensors, even with the use of the same reflection wavelengths. The possibility of measuring the temperature has been experimentally demonstrated.

基于自扫描光纤激光器的相干光频域反射仪在传感领域的应用

摘要

提出的第一个结果证明了基于自扫描光纤激光器的相干光频域反射仪的适用性。各种光纤布拉格光栅（FBG）的阵列用作感测线。结果表明，反射光谱位于我们光源扫描范围之外的FBG可以用于已开发的反射仪中。使用频域反射法技术，即使使用相同的反射波长，也可以执行FBG传感器的空间分离。已经通过实验证明了测量温度的可能性。
