Recent advances in devices and applications of high-birefringence fiber loopmirror sensors are addressed. In optical sensing, these devices may be used as strain andtemperature sensors, in a separate or in a simultaneous measurement. Other describedapplications include: refractive index measurement, optical filters for interrogate gratingsstructures and chemical etching control. The paper analyses and compares different types ofhigh-birefringence fiber loop mirror sensors using conventional and microstructured opticalfibers. Some configurations are presented for simultaneous measurement of physicalparameters when combined with others optical devices, for example with a long periodgrating.
本文探讨了高双折射光纤环形镜传感器在器件和应用方面的最新进展。在光学传感中，这些器件可单独或同时用作应变和温度传感器。其他所述应用包括：折射率测量、用于询问光栅结构的光学滤波器以及化学蚀刻控制。本文分析并比较了使用传统光纤和微结构光纤的不同类型的高双折射光纤环形镜传感器。还介绍了一些与其他光学器件（例如长周期光栅）组合时用于同时测量物理参数的配置。
