摘要
本文对法布里-珀罗高温应变传感器技术的发展进行了整理和总结。基于石英光纤的法布里-珀罗高温应变传感器能够应用于1000℃以下的环境,采用本征型和非本征型F-P传感器均能够对应变进行测量。对于1000℃以上的环境,以蓝宝石光纤为基础制作的传感器取得了较好的测温效果,但对应变的测试没有报道。基于蓝宝石光纤的F-P腔高温应变测试将会是未来的发展方向之一。
The progress of fiber optic Fabry-Perot high temperature stain sensor is summarized. The Fabry-Perot sensor based on silica fiber can be applied to structure strain test up to 1000℃. Two styles of Fabry-Perot interferometry which are intrinsic Fabry-Perot interferometry （IFPI） and extrinsic Fabry-Perot interferometry （EFPPI） can both be applied to structure stain measurement under high temperature circumstance. The sapphire fiber Fabry-Perot sensor can be applied to obtain temperature parameter up to 1600 ℃. And no report is presented for sapphire fiber Fabry-Perot sensor for structure strain measurement under high temperature circumstance. However, we believe that the strain measurement of high temperature structure by sapphire fiber Fabry-Perot will be happened in near future.
