Distributed optical fibre sensing in synthetic fibre ropes and cables
نویسندگان
چکیده
Distributed strain measurements on synthetic fibre ropes as used in marine applications are reported. The ropes incorporate single mode fibre-optic sensors for strain measurement. A Brillouin-amplification-based distributed strain measuring system has been utilised to interrogate the fibre sensors incorporated into a parallel yarn aramid rope. Initial results are presented to conclusively demonstrate the technical feasibility ofthe approach

متن کاملHigh Frequency Distributed Optical Fibre Dynamic Strain Sensing: A Review
The concept of using an optical fibre to map dynamic perturbations along the sensing fibre was first proposed by Taylor et al. (Taylor 1993) in 1993 and later demonstrated by his team in 2005 (Juarez 2005). The proposed sensor was only capable of detecting the dynamic perturbations along the sensing fibre by monitoring the changes in the pattern of the backscattered coherent Rayleigh noise (CRN...
متن کاملDistributed temperature sensor system based on Raman scattering using correlation-codes
Introduction: Fibre-based distributed temperature sensor (DTS) systems have been intensively studied for several years, because of the advantages they can provide compared to conventional sensors, and to optical fibre multiplexed sensor systems (such as grating-based sensors); most common applications include pipeline monitoring (for oil and gas transportation), oil well monitoring and power ca...
متن کاملCharacterization of Flexible Copolymer Optical Fibers for Force Sensing Applications
In this paper, different polymer optical fibres for applications in force sensing systems in textile fabrics are reported. The proposed method is based on the deflection of the light in fibre waveguides. Applying a force on the fibre changes the geometry and affects the wave guiding properties and hence induces light loss in the optical fibre. Fibres out of three different elastic and transpare...
