摘要

聚酰亚胺涂层光纤光栅对相对湿度和温度的变化有线性响应。Blue Road Research正在使用这种技术来监测相对湿度，并使用涂有丙烯酸酯的光栅来监测温度。本文介绍了一些用于简单和多路相对湿度和温度传感器的传感器和读出系统。此外，还描述了一种间接监测土壤湿度的方法。

Measuring humidity and moisture with fiber optic sensors

Polyimide coated fiber Bragg gratings have a linear response to changes in relative humidity and temperature. Blue Road Research is using this technology to monitor relative humidity and using acrylate-coated gratings to monitor temperature. This paper describes some of the sensors and readout systems for simple and multiplexed relative humidity and temperature sensors. Additionally, an indirect method for monitoring soil moisture is described.
