Fiber Bragg Grating Sensor

Fiber Bragg Grating (FBG) temperature sensors use Bragg Fiber Bragg Grating (FBG) as the sensitive element, combined with a FBG demodulator (FBG analyzer), for temperature detection and monitoring of the measured object and environment. This type of sensor is also commonly referred to as FBG thermometer, fiber Bragg grating temperature probe, or FBG temperature probe.
