Temperature Sensing FBGS Temperature Sensing The reflection wavelength of the Fiber Bragg Grating depends on the grating characteristics (period, modulation) and is influenced by the ambient conditions such as strain and temperature. This allows the …

Fiber Bragg grating temperature sensor with controllable ...

+

We demonstrate a fiber Bragg grating (FBG) sensor with controllable sensitivity by connecting two metal strips that have different temperatureexpansion coefficients. By changing the lengths of the metal strips we successfully controlled and improved the temperature sensitivity to times of that of bare FBG.
