Fiber Bragg Grating Sensors
Non invasive FBG sensors installed on the Colleoni statue by A. Verrocchio in Venice, during the restoration of what is considered one of the most important equestrian monument of the Italian
Strain transfer of fiber Bragg grating sensors in fiber-reinforced
A new unified strain transfer model is proposed to quantify measurement loss of fiber Bragg grating (FBG) sensors in CFRP. The effect of geometric factors of CFRP on strain transfer
Tilted Fiber Bragg Grating Sensors | Springer Nature Link
Tilted fiber Bragg gratings (TFBGs), i.e., tilt of the grating plane breaking the cylindrical symmetry of the fiber, are inscribed in standard telecom single mode fiber without physical modification, which
A Guide to Fiber Bragg Grating Sensors
Therefore FBG is essentially a sensor of temperature and strain but, by designing the proper interface, many other measurements can be made to impose perturbation on the grating resulting in a shift in
Simulation and Experiment of Tilted Fiber Bragg Grating Humidity Sensor
To address these issues, this study proposes a novel tilted fiber Bragg grating (TFBG)-based optical fiber humidity sensor, coated with a composite film of polyvinyl alcohol (PVA) and
