“…The combination of FLRD technology with Frequency Shift Interferometry (FSI) is also a trending research direction, providing enhanced methods for the sensitivity, multi-channel monitoring, and real-time data acquisition of sensors. Cheng et al [86] integrated FLRD sensors with frequency-shifted interferometric measurements for large-strain measurements, achieving a sensitivity of 0.34 km −1 •mε −1 and a dynamic range of 5 me. Chen et al [87] similarly combined FLRD sensors with FSI for large-strain measurements, utilizing a dual-tapered multimode optical fiber as the sensor head.…”
