Abstract

A simple fiber-optic temperature sensor is constructed that uses the temperature dependence of microbending loss. The sensor is tested and shows high sensitivity and a strict linear scale over a wide range from 20 to 180 K. It is shown that a proper choice of signal wavelength can be used either to make the sensor more sensitive or to make it independent of changes in laser wavelength.

摘要

构建了一种利用微弯损耗与温度的相关性的简单光纤温度传感器。对该传感器进行了测试，结果表明它在20至180K的宽范围内具有高灵敏度和严格的线性刻度。结果表明，适当选择信号波长可用于使传感器更灵敏或使其与激光波长的变化无关。
