Abstract

A novel SOA-based, dual-wavelength, FBG laser sensor system for simultaneously measuring vibration, temperature and humidity is demonstrated. The sensor interrogations are completed with a wavelength matching method by adjusting temperatures of two TECs to control wavelengths of two reference FBGs matching with those of two sensor FBGs. Two corresponding TEC control signals are used as detection outputs for temperature and humidity measurements. Some experimental results on simultaneous measurements of vibration, temperature of the sensor system with a FBG vibration/temperature senor and a 10-layer polyimide coating FBG humidity sensor are presented. The fundamental system performances in respects of the frequency response of system in vibration measurements and the tracing of the Bragg wavelength of sensor FBG through a TEC temperature control method were also demonstrated. The experimental results verified that the proposed FBG laser sensor system has a desired detection performance. This sensor system can be used in many industrial measurement fields, particularly in the electrical power industry for condition monitoring of power generators as well as high-voltage power transformers.
