Paper Abstract

Fiber optic sensors are potentially very well suited for condition monitoring of environment, materials, structures, and facilities. However, there is a long way from a laboratory prototype to a reliable industrial sensor system. Based on the examples of two fiber Bragg grating systems, both used for long term monitoring of strain and temperature on bridges, general sensor system reliability will be discussed. In addition, specific reliability considerations and lifetime tests, especially for optical fibers and Bragg gratings, coatings, and adhesives will be presented.
