Paper Abstract

We present recent progress on the commercial development of optical fiber strain gages for both static and dynamic applications up to 1650°C. The low mass and all dielectric nature of optical fiber sensors resists debonding in high vibration environments and completely eliminates noise induced by electromagnetic fields. In addition, the fiber sensor design ensures that it is shielded from surface shear strains that typically lead to debonding and fracture of wire filament gages exposed to long-term cyclical loading.
