Full textStructural Health Monitoring is a key factor in life-cycle management of civil structures. Truly distributed fiber optic sensors, composed by an optoelectronic device paired with an optical fiber in a cable, provide strain profiles over several kilometers with a centimeter resolution. They are thus able to provide relevant information on large structures. However, a preliminary performance assessment is required prior to any industrial application. Due to shear deformation of the cable's protective coating, strain measurements provided by the measuring system may differ from actual strains in the embedding medium. A methodology, based on mechanical tests and modelling, was thus developed to determine the relationship between measured/actual strains. It was applied to determine the mechanical response of a specific cable embedded in concrete. Performance assessment method was applied to a specific measuring system. Tests were carried out under laboratory conditions on the fiber optic cable, out of the concrete medium in a first stage, and then embedded in concrete structures. It enabled to evaluate its components and standard uncertainties. The cable could not be replaced after being embedded in concrete. It is necessary to evaluate the ageing effects on its mechanical properties to use it for a long term period. A specific study was carried out to determine the cable durability under chemical, thermal and mechanical solicitations

Full textTo date, an effective Tsunami Early-Warning System (TEWS) at a global scale is not yet in place. This reflects a proverbial challenge in geosciences: To instrument the world's ocean floors and conduct long-term observations with sufficient spatial and temporal coverage. A paradigm in the form of a novel photonic technology has been proposed for truly multi-scale monitoring, whilst keeping costs relatively low. Distributed Acoustic Sensing (DAS) uses optical fibers themselves to measure the spatial distribution of environmental properties along every point of the optic fiber. By leveraging the more than one million kilometers of optical fiber laid across the continents and oceans, the scientific community stands to gain permanent, global monitoring network of densely-spaced, highly sensitive single-component sensors, capable of providing continuous real-time data. Although it's been shown that DAS is capable of recording long-period oceanographic phenomena such as tides and gravity waves waves, and empirical observations of sensitivity to seafloor pressure variations; the pressure detection mechanism in DAS remains to be quantitatively described.Within this context, this thesis aims to provide a proof-of-concept of a specific DAS architecture (phase-sensitive detection employing chirped laser pulses) suitable for TEWS applications. Towards this objective, this work assessed the sensitivity required, and considers DAS instrument performance to ascertain detection of tsunami waves. A derived model of the expected seafloor strains potentially induced by tsunami waves is presented and finds seafloor compliance and the Poisson effect on the cable as the primary mechanisms through which DAS is anticipated to record the passage of tsunami waves. The analysis of the derived model is supported by fully coupled 3-D physics-based simulations of earthquake rupture, seismo-acoustic waves and tsunami wave propagation. Furthermore, as most instrumentation, the sensitivity at low frequencies is primarily hindered by 1/f instrument noise. This work identifies several enhancements in the opto-electronic hardware towards reducing instrument noise, and increase of sensitivity to low-frequency signals relevant to tsunami signals, specifically in the 1-10 mHz regime. The theoretical analysis and numerical simulations presented in this work point to the real possibility of detecting tsunami waves using fiber optic cables

Full textWith the growing demand for internet bandwidth, having robust optical communication systems is more crucial than ever. Beyond the advances in individual technologies and components, the performance of the communication system also depends on how intelligently these components are used and combined so that the overall configuration is optimized. Often, network performance is limited by predeployment predictions, making accurate estimation essential for optimization. The objective of this thesis is to characterize and monitor key sources of distortion in subsea links, primarily to predict the network’s future performance with minimal margins. We focused on two physical impairments: nonlinear Kerr effects and polarizationdependent loss. The thesis addresses the challenges of performance estimation and network monitoring to introduce novel monitoring tools and provide guidelines for optimizing transmission systems

Full textIn the framework of Cigéo, the future underground repository for long-lived radioactive waste, the monitoring of the structures must be guaranteed for almost a century to ensure its reversibilit. The horizontal repository cells will be loaded by 500 m of rock which will reduce their section over time. This reduction, called convergence, must be monitored by sensors with resistance to harsh environment, low intrusiveness, proper sensitivity. We propose the use of distributed optical fiber strain sensing cables, whose strain measurements are used to calculate convergence via an inverse-analysis finite-element method, using Brillouin and Rayleigh backscatterings. The method is described, assessing the influence of structural parameters and measurements noise on its sensitivity. We validate it in a laboratory test, in controlled conditions and underground, reproducing convergences up to the representative value of 10 mm on a mock-up of the high-level waste repository cell. We compare two fixation methods and loading schemes, using other sensors as reference. Results show how distributed optical fiber sensors can achieve the required 1 mm of resolution, close to standard methods. The fibers have been firstly analysed under the coupled effect of temperature and radiation up to a total γ-rays dose of 1 MGy. Temperatures around 100°C preserve the fiber functioning better than being at room temperature. A specific cable for strain sensing, with a radiation resistant fiber inside, is then developed and tested, reporting that temperature and strain sensitivities and the mechanical behaviour remain stable up to 500 kGy. We evaluate also the role of the protective layers of the tested cable and its plastic behaviour up to 10000 με

Full textLes fibres optiques « multimatériaux », sont définies comme des guides optiques où le cœur et la gaine de la fibre optique sont composés de matériaux de composition ou de nature différentes. Ces fibres attirent l'attention de plus en plus de chercheurs, et ce dans de nombreux pays, car selon les différentes compositions des verres, ces fibres optiques peuvent présenter des propriétés originales. Dans cette thèse , après une présentation des procédés de fabrication bien connus et d'autres plus originaux, nous proposons de développer le procédé « poudre » pour fabriquer deux fibres multimatériaux originales. La première est une fibre à bande interdite photonique composée d'un cœur de silice et d'un cristal photonique bidimensionnel d'inclusions d'un verre de Silice Aluminium Lanthane. Ce verre permet de développer ce type de fibre avec des inclusions dont l'indice de réfraction est plus important que la plupart des fibres à bande interdite rapportées. Les propriétés de ces fibres ont été étudiées ce qui à conduit à la conception et la fabrication d'une fibre optimisée. La deuxième fibre étudiée comprend des fils métalliques de cuivre. Nous avons étendu le procédé de fabrication aux fibres verre / métal. Un câble coaxial de taille micrométrique a été modélisé, optimisé et réalisé pour démontrer l'intérêt d'une telle structure pour guider des signaux micro-ondes à 100 GHz. Les procédés développés pour la fabrication des ces deux fibres associent le procédé « poudre » et le procédé « stack-and-draw »

Full textDistributed Acoustic Sensing (DAS) is a new technology of seismic acquisition that relies on traditional fibre-optic cables to provide inline strain measurement. This acquisition system is largely used in vertical seismic profiling (VSP) surveys. Coupling is a key factor influencing data quality. While geophones and accelerometers are clamped to the borehole wall during VSP surveys, the fibre cable is either clamped and then cemented behind the casing, or attached with rigid clamps to the tubing, or loosely lowered into the borehole. The latter deployment strategy, also called wireline deployment, usually acquires the lowest level of signal but is regarded as the most cost-effective in particular for existing well installations. This PhD thesis addresses the problematic of coupling of DAS using wireline deployment. We develop numerical models that are used to analyse real data. The interpretation of these results allows us concluding that an immediate contact of the cable with the borehole wall with a computed contact force is required to provide good coupling conditions. Based on those findings, we propose solutions to further optimise DAS acquisitions. We numerically modify the contact force and the elastic properties of the DAS cable and show how these modifications can improve but also deteriorate data quality. Finally, we propose a coupling detection algorithm that is applied to real datasets and allows ensuring the acquisition of data with a high signal-to-noise ratio
