The modal power distribution technique is applied to a multimode optical fiber embedded in a three-dimensional composite material for real-time characterization and monitoring of the structure. The measurements on the modal power distribution within these fibers, and the subsequent redistribution induced by external perturbation, indicate that the modal power distribution technique is more sensitive than the intensity-modulation technique for smart-structure characterization.
