Fiber Bragg Grating Sensors
A variation of the period of the grating inscripted in a fiber optic – induced by mechanical or thermal perturbation – causes a shift of the reflected peak wavelength, due to the related optical path length
Progress of fiber Bragg grating sensors in state perception of
Large space demand and expensive cost restrict the application of distributed fiber sensors in small and medium-sized equipment. Fiber grating sensors, especially fiber Bragg grating
Fiber Bragg grating
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others.
Mechanisms of signal coupling to optical fiber for FBG sensor
One of the major challenges when using fiber Bragg grating sensors (FBGs) to detect Lamb wave or acoustic emission signals in structures is the low sensitivity of these sensors to surface waves
