Abstract

Advantages of optical fiber Bragg grating sensors at low temperatures, are electrical isolation, low electro-magnetic interference, low thermal conductivity to a large number of multiplexed sensors. They show negligible thermo-optic and magnetooptic effects in cryogenic environment. These properties make them attractive for temperature surveillance and structural health monitoring of cryogenic systems, or for the testing of material properties and system components at low temperatures.
