A Dual-Dip Heterogeneous LPFG Sensing System via Annealing under Bending with Temperature and Humidity Compensation
Cuiying Huang, Riming Xu, Jialing Kang +4
Optical fiber multi parameter sensing is fundamentally constrained by cross-sensitivity and the complexity of multi sensor integration. Here, we present a dual-dip heterogeneous lo…

Multi parameter discrimination using multiple spectral troughs in a cascaded fiber sensor
Riming Xu, Yanbo Li, Xingnan Chen +1
Accurate monitoring of temperature, axial strain, and refractive index is critical for structural health monitoring, industrial process control, and environmental sensing. However,…
