Fiber Bragg Grating Sensor

Optical Fiber Sensing and Structural Health Monitoring Technology, 2019
According to the optical structure and sensing principle, fiber gratings are divided into phase shift grating, chirped grating, blazed grating, long period grating, and Bragg grating. Based on the basic principle and theoretical analysis of fiber Bragg grating, this chapter systematically introduces and analyzes the sensing principle, structure design ...

Discrimination between strain and temperature effects of a single fiber Bragg grating sensor using sidelobe power

, 2020
A fiber Bragg grating (FBG) is one of the most common and widely used fiber optic sensors. One main issue when using a FBG-based sensor is that it is simultaneously sensitive to both the strain and the temperature, and compensation for the temperature ...

Tilted fiber Bragg grating sensors

Laser & Photonics Reviews, 2012
AbstractOptical fiber gratings have developed into a mature technology with a wide range of applications in various areas, including physical sensing for temperature, strain, acoustic waves and pressure. All of these applications rely on the perturbation of the period or refractive index of a grating inscribed in the fiber core as a transducing ...
