Abstract :
A novel SOA-based, FBG two-wavelength laser sensor system for simultaneously measuring vibration, temperature and humidity is demonstrated. The sensor interrogations are completed with a wavelength matching method by using TECs to control wavelengths of two reference FBGs matching with those of two sensor FBGs, and the corresponding control signals are used as detection outputs.
