Abstract

We report the experimental results on a new infrared fiber-optic pyrometer for very localized and high-speed temperature measurements ranging from 170 to 530 °C using low-noise photodetectors and high-gain transimpedance amplifiers with a single gain mode in the whole temperature range. We also report a shutter based on an optical fiber switch which is optically powered to provide a reference signal in an optical fiber pyrometer measuring from 200 to 550 °C. The tests show the potential of remotely powering via optical means a 300 mW power-hungry optical switch at a distance of 100 m, avoiding any electromagnetic interference close to the measuring point.

摘要

我们报告了一种新型红外光纤高温计的实验结果，该高温计用于非常局部化且高速的温度测量，测量范围为170至530°C，使用低噪声光电探测器和在整个温度范围内具有单一增益模式的高增益跨阻放大器。我们还报告了一种基于光纤开关的快门，该快门由光供电，用于在测量范围为200至550°C的光纤高温计中提供参考信号。测试表明，通过光学方式在100米的距离上为一个功耗为300毫瓦的高功耗光学开关远程供电是可行的，避免了测量点附近的任何电磁干扰。
