The sensitivity of the FBG temperature sensor is sometimes referred to as the resolution or temperature sensitivity of the sensor, that is, the minimum temperature change that the sensor can measure.
To be precise, the sensitivity of each FBG temperature sensor is different, mainly determined by the reflection wavelength of the FBG and the natural characteristics of the glass filament used in the fiber, and sometimes it is also related to the sensor packaging method. The method can sensitize or desensitize the FBG. less
