High Efficiency Generation of Acoustic Modes in Optical Fibers
Abstract
Abstract approved for public release: This proposal addresses the high efficiency generation of acoustic modes in and their propagation with low attenuation through optical fibers. The acoustic waveguide actuators and sensors will be used for imaging of damage in a structure. Experimental investigations will be pursued in the wrapping of optical fibers with CNT arrays using a previously developed winding process. Applying the proposed sensor technology to structural health monitoring of large structures introduces the multiple challenges of adequately covering surface areas of complex structures, adapting to changes in the structure over the lifetime of the structure, and providing localized, high-resolution imaging of structural defects in regions not necessarily known a-priori.
