We have designed, fabricated, and characterized a fiber-optic three-dimensional vector
accelerometer for vibration measurement. The accelerometer is based on fiber Bragg …

In this study, the implementation of an optical accelerometer unit based on fiber Bragg
gratings, suitable to monitor structures with frequencies up to 45 Hz, is reported. The …

We have implemented a multipoint two-dimensional curvature optical fiber sensor based on
a nontwisted homogeneous four-core fiber. A theoretical approach to model the mechanical …

In recent years, multicore fiber (MCF) has attracted increasing interest for sensing
applications, due to its unique fiber structure of multiple parallel cores in a single fiber …
