A fast and wideband wavelength-swept laser (WSL) utilizing the reconstruction-equivalent-chirp (REC) technique, integrated with 24 DFB lasers, is proposed and experimentally demonstrated. Additionally, a high-speed FBG sensing system using field-programmable gate arrays (FPGAs) is proposed and demon...
