A Fiber-Optic Interferometric Sensor with multiplexing capability and noise free behaviour of the leading fiber is presented. The FOIS is based on a differential scheme, where both the reference and the sensing beam are guided by the same polarization maintaining fiber. A microprobe realized with-stacked optics technology permits the measurements in harsh environment. A full comparison of the noise-rejection capability of the realized FOIS versus a conventional ones is made. The experimental results confirm the high-noise rejection features of the developed FOIS.

Abstract
A Fiber-Optic Interferometric Sensor with multiplexing capability and noise free behaviour of the leading fiber is presented. The FOIS is based on a differential scheme, where both the reference and the sensing beam are guided by the same polarization maintaining fiber. A microprobe realized with-stacked optics technology permits the measurements in harsh environment. A full comparison of the noise-rejection capability of the realized FOIS versus a conventional ones is made. The experimental results confirm the high-noise rejection features of the developed FOIS.File in questo prodotto:
