Note (General): This thesis proposes a semicircular hetero-core optical fiber triaxial accelerometer composed only of fibers. We realized a fiber optic accelerometer with low transverse sensitivity by adjusting the position of the hetero-core fiber sensor into a semicircular shape. A triaxial accelerometer was fabricated using three uniaxial hetero-core optical fiber accelerometers, which were orthogonally arranged each other. The measurement error mainly based on the transverse sensitivity was reduced by using a 3×3 sensitivity matrix compared to the sensitivities in the primary axis. The sensitivity in the lowfrequency range was successfully improved by placing weight at the center of the semicircular arc of the optical fiber. For structural health monitoring, a multimodal sensing system composed of the fiber optic accelerometer and a liquid detection sensor, whose temporal waveforms in the optical loss could be discriminated successfully. The obtained results in this thesis have successfully demonstrated the fiber optic accelerometer in practical usage.
