The use of an improved technique to reduce the variability of output voltage in real-time Fibre Bragg Grating based monitoring system

Fibre Bragg Grating (FBG) sensors have been widely utilized in the structural health monitoring (SHM) of structures. However, one of the main challenges of FBGs is the existence of inconsistency in output voltage during wavelength intensity demodulation utilizing photodetector (PD) to convert the li...
