Title:
レイリー後方散乱信号を使用する過酷な環境での温度又は変形の分散測定の為の光ファイバを生産する方法
Document Type and Number:
Japanese Patent JP7423617
Kind Code:
B2
Abstract:
An optical fibre, for use in the field of distributed measurement of temperature or deformation by optical reflectometry in the frequency domain using the Rayleigh backscattered signal in the fibre, includes a core doped with nanoparticles for example formed from gold particles covered with zirconium oxide, and can be subjected to high temperatures during the measurement. A method for producing the optical fibre includes a step of heat treatment during which the optical fibre is subjected, for a duration of at least one hour, to a heat treatment temperature higher than a maximum temperature to which it will be subjected during a measurement.
