Abstract:
The fibre-optic interferometric hydrophone has been widely used in ocean acoustic applications. There are many different hydrophone systems in use. They can generally be classified as hull mounted, towed, or fixed (bottom mounted and vertical) array systems. Different optical architectures have evolved for each of the areas, which make a good case study on what aspects of a particular application influence the optical architecture. A novel architecture of fibre-optic hydrophone based on PMDI is theoretically and experimentally discussed in this paper. A novel optical configuration is proposed, and the modulation and demodulation system is built. A series of experiments are designed to analyse the characteristics of this system. The results of the experiments show that this type of fibre-optic interferometric hydrophone array has many advantages such as low noise, a large dynamic range.

Abstract:
In this thesis, my main focus was to establish a novel composite-cavity fibre laser (CCFL) and to apply it in sensing, particularly in the hydrophone application. The CCFL that I have proposed is formed by writing three wavelength matched fibre Bragg gratings directly into a continuous length of doped fibre. I have also examined the relative advantages and disadvantages of interferometric and intensity-based hydrophone systems, and have established a hydrophone system that can be switched between the two modes of operation, by making use of digital signal processing. I have established a theoretical model to study the lasing and spectral characteristics of the CCFL. My analysis showed that whilst the CCFL have significantly different phase and threshold conditions from the common semiconductor diode lasers with external cavity, the CCFL also have mode-limiting properties that are often sought after. Through simulations, I was able to identify that a non-uniform straining scheme, that is, when one of the sub-cavities of the CCFL is restrained from strain, can improve the sensitivity with respect to existing single cavity fibre lasers, in both the frequency and intensity domains. My simulations also showed that the sensitivity of such a straining scheme can be optimised by tuning the reflectivity of the gratings, sub-cavity lengths, doping concentration and pump power. I have fabricated multiple CCFLs using the in-house grating writing facilities, and have experimentally assessed their power and spectral related lasing characteristics. Whilst having a significantly longer total cavity length compared to typical fibre lasers, the CCFLs demonstrated stable single longitudinal mode operation and narrow linewidth in the order for a few tens of kHz. Asymmetric output power and frequency as a result of unequal sub-cavity lengths were also examined. Finally, I conducted sensing experiments by applying the CCFLs in strain monitoring and intensity-based hydrophone. My results showed that the non-uniform straining scheme had significantly improved the intensity response of the CCFL, and that the acoustic pressure and frequency can be determined by directly sampling and applying Fourier transform to the output intensity of the fibre laser.

Abstract:
This thesis is composed of two distinct parts. The first part of this work addresses the problem of critical ignition behind a decaying shock wave in the context of cellular detonations. Low-pressure (4.1 kPa) shock tube experiments were performed in a thin rectangular channel using the highly-unstable mixture of CH4 + 2O2 and the weakly-unstable mixture of 2H2 + O2 + 7Ar, with Schlieren visualization of the flow field. The dynamics of the lead shock in a detonation cell was reconstructed from measurements of the lead shock position and curvature. The post-shock state and the expansion rate along the path of a Lagrangian particle crossing the lead shock at any given point in the cell cycle were evaluated with the shock jump and shock change equations. The chemical evolution behind the shock was then integrated using a detailed chemistry model. Quenching of the post-shock reaction zone was found within the first half of the detonation cell for both mixtures, with quenching occurring earlier in the highly unstable mixture. Simplified models derived from 1-step and 2-step chemistry models very accurately predict the quenching of the post-shock reactions and the evolution of the ignition delay through the cell. The second part describes the assembly and characterization of a fibre-optic probe hydrophone (FOPH) for the measurement of shock waves associated with blast-induced neuro-trauma. Compared to traditional polyvinylidene difluoride (PVDF) hydrophones, the assembled FOPH has a higher bandwidth and smaller active diameter, which are comparable to the characteristic time and thickness of shock waves associated with blast-induced neuro-trauma. However, the sensitivity of FOPHs are substantially lower than traditional hydrophones. We assemble a FOPH and provide detailed calculations and measurements of its sensitivity (0.66 mV/MPa) , noise floor, and spatial resolution. The 150 MHz bandwidth, limited by the photodetector, is sufficient for resolving shock waves with over-pressures of up to 174 kPa with 3 measurement points. Experimental measurements of the system noise gives a floor of 260 Pa/√Hz . A detailed noise analysis finds that the system is limited by photodetector noise (215 Pa/√Hz), which is 4x the fundamental shot noise limit, closely followed by a laser noise of 150 Pa/√Hz. We conclude that the system noise floor is insufficient for resolved measurements of the post-shock pressure in the range associated with blast-induced neuro-trauma. From our noise analysis, we quantify the sensitivity enhancement required for resolving this regime, and we conclude that sensitivity-enhancing fibre-coatings could provide a sufficient increase in sensitivity.

Full text
Abstract:
This thesis documents the development of a novel fibre optic hydrophone, for the characterisation of medical ultrasound transducers and the measurement of ultrasound induced temperature rises. The transduction mechanism of the hydrophone is based on the detection of acoustically and thermally induced changes in the optical thickness of a Fabry-Perot interferometer deposited at the tip of a single mode optical fibre. The interferometer comprises a layer of Parylene-C sandwiched between two thin gold mirrors. The design of the sensor was optimised using a numerical model of the interferometer transfer function. Through the use of vacuum deposition techniques, a fabrication procedure has been developed which enables batch production of the sensors. A self contained sensor interrogation system has also been developed. The system uses a rapidly tuneable laser developed originally for the telecoms industry to interrogate the sensor and make acoustic and thermal measurement, Control of the system is achieved via a PC using software written in Labview 8.0.

Abstract:
Il a été montré que la cavitation acoustique pouvait se révéler utile dans l'administration de médicaments pour de nombreuses applications biologiques et médicales. Cette thèse commence par une présentation de la cavitation ultrasonore et des mécanismes d'action mis en jeu pour la délivrance de médicaments. A la fin de ce cette synthèse, un dispositif à deux transducteurs ultrasonores disposés de manière confocale est présenté pour résoudre certains des problèmes actuels dans le domaine. Il est ensuite mis en oeuvre dans différentes études de faisabilité. La thèse est organisée en 5 chapitres : 1. L'utilisation de la cavitation acoustique dans un contexte biomédical est présentée ici dans une revue générale. Ce chapitre comprend l'état de l'art pour la génération de cavitation, les techniques expérimentales qui sont actuellement mises en oeuvre pour la mesure de la cavitation, et les approches cliniques et précliniques pour l'utilisation de la cavitation in vivo pour différents types de tissu biologique. 2. Le dispositif ultrasonore utilisé pour toutes les études de cette thèse est ensuite décrit. Il est caractérisé acoustiquement et comparé avec un simple transducteur dans le but de démontrer son efficacité pour la génération de la cavitation. Cette comparaison est d'abord faite par une quantification chimique du niveau de cavitation. A puissance constante, le dispositif à deux transducteurs confocaux est bien plus efficace pour générer de la cavitation. Les causes de cette observation, notamment la réduction de la propagation non-linéaire et la stabilisation du nuage des bulles par les forces Bjerknes, sont ensuite étudiées par des mesures acoustiques, des simulations de pression en régime linéaire et un suivi par une caméra ultra rapide des nuages de bulles induits. 3. Le prototype confocal est utilisé in vivo sur des tumeurs sous cutanées en conjonction avec des liposomes. Dans un premier temps, des essais sous IRM démontrent la possibilité de larguer le contenu des liposomes localement par la cavitation inertielle délivrée par le dispositif. Une seconde étude avec une formulation liposomale de doxorubicine a permis de démontrer l'amélioration de la réponse thérapeutique de la chimiothérapie après application de la cavitation inertielle.. 4. Une étude de faisabilité de l'interférence de l'ARN (RNAi) sur un petit nombre d'animaux est réalisée avec le dispositif confocal et des molécules de siRNA encapsulées dans des liposomes Les expériences sont conduites in vivo avec une xénogreffe de tumeur de sein humain. Après une phase de réglage des paramètres ultrasonores pour limiter la toxicité du traitement, on observe une inhibition significative du gène ciblé. 5. Une deuxième étude de faisabilité est réalisée pour étudier la potentialisation de la chimiothérapie avec l'évérolimus dans un modèle de chondrosarcome de rat. Les traitements ultrasonores et les chimiothérapies sont répétés. Sur un petit nombre d'animaux, on montre l'innocuité du traitement ultrasonore, et l'efficacité en conjonction avec l'agent anti tumoraux, évérolimus
Acoustic cavitation has been shown to be a useful tool in drug delivery for many different biological tissues and indications, and this thesis aims to contribute to the knowledge of cavitation from a drug delivery perspective. This thesis seeks to synthesize the current knowledge and practice concerning acoustic cavitation in a biomedical context, and to present a high intensity confocal ultrasound (US) prototype to address some of the current problems in the field and to give a proof of concept for the therapeutic efficacy of such a prototype. The thesis is organized in 5 chapters: 1. The use of acoustic cavitation in a biomedical context is presented here in a general review. This review comprises the state of the art for cavitation generation, experimental techniques currently being implemented for the measurement of cavitation, and the clinical and preclinical approaches to the use of cavitation in vivo on a tissue by tissue basis. 2. The high intensity confocal US prototype used for all studies in this thesis is presented here. It is characterized in terms of the advantages it gives for the generation of cavitation. Enhancement of cavitation is first demonstrated chemometrically with a fluorescent dosimeter compared to a single transducer at the ultrasonic focus. The mechanisms for cavitation enhancement are then investigated with acoustic measurements, linear pressure simulations, and high speed camera data. 3. The confocal US prototype in used in conjunction with a liposomal formulation of doxorubicin is performed in which a therapeutic enhancement of tumor inhibition is presented. The mechanism of this enhancement is investigated with liposomally encapsulated lanthanide contrast agents and magnetic resonance imaging. 4. A small scale proof of concept for the use of RNA interference using the confocal prototype, and liposomally encapsulated siRNA molecules. The experiments are performed In vivo with a xenograft of human breast tumor. This study also includes data for the safety of the US exposure on a mouse treated one time. 5. Another small scale proof of concept of the use of the confocal device on potentiating chemotherapy with the drug everolimus in a rat chondrosarcoma model. The studies presented here also investigate the use of multiple US exposures on the same tumor in a combined drug / US treatment regimen

Abstract:
Dual purpose fiber optic microbend loss sensors have been developed for measurement of underwater acoustic wave amplitudes and for detection of the direction of wave propagation. Cylindrical sensing elements with external threads have fibers wound around them. Axial slots, cut along the length of the cylinder and deeper than the threads, provide the microbends. Three different construction schemes for cylindrical sensing elements are built. The dual purpose hydrophones are characterized for frequencies ranging from 15 kHz to 75 kHz. Based on the results, an improved design that uses the wavelength dependence of microbend loss in a single mode fiber is proposed.

Abstract:
Ultrasonic imaging uses higher ultrasound frequencies and power levels to achieve better spacial resolution and image quality. Potential hazard for patients have to be evaluated on the basis of relevant acoustic parameters. Measurements of the acoustic pressure with piezoelectric hydrophones is only reliable up to 40 MHz because of minimum sensor size. This work improves a pizooptical measurement method for acoustic pressure. Acoustic pressure changes the refractive index of water. This is determined by measuring laser power, reflected at a fiber/water interface. To improve calibration uncertainty for that kind of measurement to the level of piezoelectric hydrophones (11% - 14%) was the primary goal. Therefore a piezooptic fiber hydrophone with single mode fiber and single mode light source (laser diode) is developed. The active area of the used single mode fiber type has a diameter of 5 µm. Since the fiber influences sound field propagation due to reflection and diffraction, sensitivity of the device is frequency dependent. These effects are compensated by mathmatic modelling. By calculaing the exact curve progression of the factor of reflection depending on the refractive index gradient at the fiber/water interface, calibration uncertainty is improved from 18% to below 11%. Results are validated by intercomparison with several calibarted piezoelectric hydrophones. Measurements are carried out on different ultrasound imagaing systems.

Abstract:
This thesis reports the advancement of two forms of Fabry-Pérot fibre optic hydrophone for the characterisation of high intensity and high pressure ultrasound fields. The first form of fibre optic hydrophone was realised using a multi-layered hard dielectric Fabry-Pérot interferometer deposited at the tip of an optical fibre. The acoustic transduction mechanism is based on the detection of acoustically induced changes in the optical thickness of the spacer layer. Several hydrophone designs were realised and an extensive investigation into the acoustic performance of the hydrophones was conducted. Each hydrophone design is anticipated to be capable of characterising acoustic fields of high pressure, with working ranges of ~90MPa. In addition, the hydrophones were shown to be able to withstand acoustic fields with intensities up to 1833W.cm-2. The frequency response of the hydrophones was measured using substitution calibration and the features of the response were investigated using a finite difference model (AFiDS). The directional response was also measured, and the hydrophones were found to be most sensitive to acoustic fields of non-normal incidence. The sensors were shown to not be subject to self-heating when interrogated by light of optical power below 3.78mW and to have a noise equivalent pressure of 30.9kPa (at 3.5MHz over a 20MHz noise bandwidth). A 3MHz frequency component was observed during the acoustic characterisation and after extensive experimentation the transduction mechanism was found to be optically sensitive and not due to the Fabry-Pérot interferometer. A second form of Fabry-Pérot fibre optic hydrophone was introduced and has previously been reported to not be able to operate at temperatures in excess of 70°C. The cause for this limitation was investigated and found to be due to the annealing of the Parylene-C spacer within the Fabry-Pérot interferometer when elevated to temperatures exceeding 56°C. The effects of annealing on the interferometer transfer function, and acoustic response were investigated. Annealing was found to produce an irreversible shift in the reflectance minimum of the interferometer transfer function, as well as a change in the frequency response of the sensor, with the features moving to higher frequencies.

Abstract:
Les fibres naturelles telles que le coton et le lin sont utilisées depuis longtemps dans l'industrie textile. De plus, elles prennent de plus en plus d'importance dans l'industrie des composites comme substituants des fibres de verre, de carbone ou d'aramide. Cependant, les fibres naturelles doivent être modifiées pour surmonter certains inconvénients tels que l'inflammabilité, l'hydrophilie et l'oléophilie. Dans ce travail, les retardateurs de flamme (RF) phosphorés et fluoro-phosphorés sont greffés par bombardement électronique et par modification chimique sur des tissus de lin afin d’améliorer leur comportement au feu, l’hydrophobicité et l’oléophobie. L'effet de la composition chimique sur le greffage a été également évalué en utilisant des fibres de miscanthus comparativement aux tissus de lin. La réactivité de la double liaison C = C des monomères phosphorés est étudiée pour contrôler l’efficacité de greffage de différents RF. Les étapes du radiogreffage sont étudiées et contrôlées. L'efficacité de greffage a été évaluée par fluorescence X et analyse par rayons X à dispersion d'énergie (EDS) / microscopie électronique à balayage (SEM). La résonance magnétique nucléaire du proton est utilisée pour analyser l'effet de l'irradiation sur les différents monomères. Le comportement au feu des tissus modifiés est étudié en utilisant l’analyse thermogravimétrique, la microcalorimétrie de combustion, cône calorimètre et un test au feu préliminaire. Des tissus ignifuges et oléophobes ont été développés avec succès
Many natural fibers have been used for a long time in textile industry as cotton and flax. Moreover, natural fibers are getting more importance in composites industry as a substitute for glass, carbon, or aramid fibers. However, they must be modified to overcome some disadvantages such as flammability, hydrophilicity and oleophilicity. In this work, phosphorus and fluoro-phosphorus flame retardants were grafted by e-beam radiation and chemical modification on flax fabrics to improve their flame retardancy, hydrophobicity and oleophobicity. The effect of chemical composition on grafting were also evaluated using miscanthus fibers in comparison to flax fabrics. The reactivity of the double bond C=C of the P-monomers was studied to control the grafting yield of various FRs. Radiation grafting steps were studied and controlled carefully. Grafting efficiency was assessed by X-ray fluorescence and Energy Dispersive X-Ray Analysis (EDX) / Scanning Electron Microscopy (SEM). Proton nuclear magnetic resonance was used to analyze the effect of irradiation on different monomers. Fire behavior of the modified fabrics was studied using thermogravimetric analysis, pyrolysis combustion flow calorimetry, cone calorimetry and a preliminary fire test. Flame retardant and oleophobic fabrics were successfully developed
