Abstract

We demonstrate a novel application of a wavelength-swept fiber laser to fiber Bragg grating sensor-array interrogation. The laser provides high signal powers of >3 mW with <0.1-nm spectral resolution over a 28-nm wavelength span. Using time-interval counting, we demonstrate static–dynamic strain measurements with a resolution of 0.47μ∊ rms at a sampling rate of 250 Hz.
