Paper Abstract

Fiber optic grating sensors have been widely used to support the measurement of strain and temperature. By appropriately constructing fiber gratings it is possible to simultaneously measure two or more environmental parameters simultaneously. This in turn results in the realization of a host of new sensing possibilities including multi-dimensional strain, shear strain in bond lines, imaging of damage in composite materials via "strain imaging" and fiber grating sensors that are capable of compensating for temperature while measuring pressure, corrosion and other environmental effects. This paper will review some of these capabilities.
