Abstract A distributed optical fiber stress and strain monitoring system (DSS) is developed based on Φ-OTDR sensing in this study. To apply the system to tunnel monitoring, dynamic and static tests of concrete beams are...

Serat optik merupakan media transmisi yang menggunakan media cahaya sebagai penyalur informasi (data) yang menawarkan kecepatan data yang lebih besar sepanjang jarak yang lebih jauh. Sistem komunikasi serat optik dengan ...

Fiber-optic distributed vibration/acoustic sensing (DVS/DAS) technology achieves breakthrough performance and explores broad cornerstone industrial applications.

Phase-sensitive optical time-domain reflectometry (Φ-OTDR) has attracted numerous attention due to its superior performance in detecting the weak perturbations along the fiber. Relying on the ultra-sensitivity of light ...

Abstract This work presents the operation of a spontaneous Raman scattering-based distributed fiber-optic temperature sensor using a commercial OTDR and a standard EDFA optical amplification in a simple and economic sche...

The phase-sensitive optical time-domain reflectometry (φ-OTDR) is a good candidate for distributed dynamic strain sensing, due to its high sensitivity and fast measurement, which has already been widely used in intrusio...

Optical fiber sensor network has attracted considerable research interests for geoscience applications. However, the sensor capacity and ultra-low frequency noise limits the sensing performance for geoscience data acquis...
