FIBER GRATING SENSORS
This chapter provides an overview of optical fiber Bragg grating sensors to measure single and multi-axis strain, pressure, temperature, moisture, vibration, acoustics, and other environmental parameters.
Fibre Bragg Grating Sensor
The FBG is inscribed into the light-guiding fiber core and encoded to form a sensor, referred to herein as the optical FBG sensor, which is composed of fiber core, cladding, and Bragg grating.
