Abstract

In this Letter we present a high temperature multipoint sensing method using sapphire fiber air gap-based extrinsic Fabry-Perot interferometers. Three sensors are fabricated and tested in a single sensing link. Experimental results show that the air gap-based high temperature sensors have a very high temperature sensitivity (>20 nm/ degrees C) and resolution (<0.3 degrees C) and are capable of operating at temperatures well above 1000 degrees C. The multiplexed sapphire sensors present a significant advancement over traditional single-point sensors for critical high temperature applications.

摘要

在这封信件中，我们提出了一种使用蓝宝石光纤气隙外差 Fabry-Perot 干涉仪的高温多点传感方法。我们在单个传感链路中制作并测试了三个传感器。实验结果表明，基于气隙的高温传感器具有非常高的温度灵敏度（>20nm/°C）和分辨率（<0.3°C），并且能够在 1000°C 以上的温度下工作。与传统的单点传感器相比，多路复用的蓝宝石传感器在关键的高温应用中是一个重大的进步。
