Paper Abstract

It has been demonstrated that Fiber Bragg Grating Sensors can measure at very low temperatures in Helium cryostats. The intrinsic temperature sensitivity is very low but can be significantly enhance by the thermal expansion of polymer carriers. Temperature and mechanical strain changes can be measured quite accurately.
