Abstract

This paper reports a high-performance FBG sensor system using a novel single-mode wavelength swept light source that can sweep wavelengths with a spectrum line width of 1 pm, a sweep range of 135 nm, and a sweep frequency of 160 Hz. This system can measure an FBG spectrum with 1-pm resolution and an FBG wavelength with 0.2-pm repeatability with a measurement frequency of 160 Hz.
