TLDR
In this paper, a novel structure of the intrinsic Fabry-Perot interference (IFPI) fiber temperature sensor is presented, which uses two different core diameter fibers and produces a reflective mirror by fusing uncoated bare fibers.Abstract:
A novel structure of the intrinsic Fabry-Perot interference (IFPI) fiber temperature sensor is presented. The sensor uses two different core diameter fibers and produces a reflective mirror by fusing uncoated bare fibers. This procedure not only solves the problem of controlling thickness and reflectance of the thin film but also provides easier and cheaper technologies for IFPI fiber sensors. Theoretical and experimental aspects of the intrinsic Fabry-Perot cavity are described. Both theoretical and experimental results from this novel structure show good agreement with those from the traditional Fabry-Perot fiber sensor.read more
