Abstract

A High temperature probe, based on a miniature fibre optic Fabry-Perot, operational temperature 700degC set by the maximum temperature of the gold plated optical fibre transceiver link used is presented. The probe is interrogated by a tuneable laser at 1300 nm, line width ~90 nm, with a second stage booster amplifier giving a maximum quasi-static output power of ~27 mW. Scanning rates of 1 kHz and 20 kHz for linear and sinusoidal scans respectively.

基于高速可调谐环形激光器的高温光纤传感器
介绍了一种基于微型光纤Fabry-Perot的高温探头,其工作温度由镀金光纤收发器链路的最高温度设定为700℃。探针由1300 nm的可调谐激光器进行探测,线宽~90 nm,第二级升压放大器提供最大准静态输出功率~27 mW。扫描率分别为1 kHz和20 kHz的线性和正弦扫描。
