This book was released on 2016 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical fiber Bragg gratings (FBGs) have been shown to provide sensing of strain and temperature at 100's of points along a fiber's path. This work extended that to 1000's of points, and added discrete sensing of magnetic field along the fiber. The first was achieved via an extension of the optical frequency domain reflectometery (OFDR) de-multiplexing method. This was done by treating FBG segments as a series of concatenated FBGs instead of one discrete FBG. Such treatment allows for the resolution of even a micro-crack's strain fields in a pressurized composite overwrapped pressure vessel (COPV), which are on the 0.5 mm scale. The second advancement of FBGs, magnetic sensing, was added via an assembly to transduce magnetic attraction into fiber strain. This assembly allowed multiplexed magnetically sensitive FBG sensors for the first time. Stringing pieces of magnetic material onto a fiber and gluing that fiber onto a structure is an easy method and largely uses off-the-shelf components. This will prove simple to expand and utilize to solve actual engineering problems. To further improve, by removing the strain transduction and thus reduce vibrational sensitivity, a new magneto-optical material is needed. An investigation into the magnetorefractive effect (MRE), and characterization of the shift of index of refraction in the material La1-xSrxMnO3 (LSMO) with magnetic field and temperature was performed. The index of refraction of the LSMO was found to shift with magnetic field. This was leveraged to create a magnetometer interferometer. That device did not function though, as the absorption of the magneto-optic LSMO used prevented light's transmission through that active material. This highlights the complex, i.e. non-real, index of refraction of LSMO an aspect which would warrant further investigation.

This book was released on 2012 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical fiber Bragg gratings offer great potential for sensing pertinent phenomena in a wide range of applications. Such range is demonstrated in this dissertation with the utilization of fiber Bragg gratings (FBGs) in two different fields of research. Both of these fields are encompassed by an overarching goal of developing smart structures capable of providing necessary feedback to enhance performance and safety. FBGs are employed in the field of structural health monitoring by measuring strain and detecting damage when embedded within AS4/3501-6 quasi-isotropic composites. The grating sensors are also utilized in the field of ferroic materials to explore novel methods of coupling external phenomena to the optical fiber reflection signal. The desire to create smart structures is carried out by developing the Bragg grating measurements system created by NASA Dryden Flight Research Center. This development involves studying the validity of strain measurements provided by embedded Bragg gratings and expanding the capabilities of the measurement system by coupling the sensors to additional types of external phenomena such as magnetic fields. Theoretical and experimental work is carried out for both phases of the dissertation. In the strain sensing phase, photoelasticity, electromagnetic wave propagation, and coupled mode theory are applied to understand the theoretical behavior of FBGs. Mechanical loads are applied to composite specimens with embedded FBGs to monitor the response of the reflection signal. Finite element analysis is then performed to further clarify how the load is transferred from the host composite to the embedded fiber. In the thermal and magnetic sensing phase, a description is given for the fabrication and experimental results of coating FBGs with thin film ferroic materials. Next, a more extensive electromagnetic wave propagation theory is described in the context of manipulating various fiber characteristics for magnetic field coupling. A FBG magnetometer is then fabricated and a magneto-optic coupling is demonstrated experimentally with an externally applied magnetic field.

Book excerpt: - Provides an overview of Fiber Bragg Gratings (FBGs), from fundamentals to applications - Evaluates the advantages and disadvantages of particular applications, methods and techniques - Contains new chapters on sensing, femtosecond laser writing of FBGs and poling of glass and optical fibers - Includes a special version of the photonic simulator PicWave(tm), allowing the reader to make live simulations of many of the example devices presented in the book. This fully revised, updated and expanded second edition covers the substantial advances in the manufacture and use of FBGs in the years since the publication of the pioneering first edition. It presents a comprehensive treatise on FBGs and addresses issues such as the merits of one solution over another; why particular fabrication methods are preferred; and what advantages a user may gain from certain techniques. Beginning with the principles of FBGs, the book progresses to discuss photosensitization of optical fibers, Bragg grating fabrication and theory, properties of gratings, specific applications, sensing technology, glass poling, advances in femtosecond laser writing of Bragg gratings and FBG measurement techniques. In addition to material on telecommunications usage of FBGs, application areas such as fiber lasers and sensors are addressed in greater detail. This special version of Picwave is limited to modelling only the passive fibre devices covered in this book. However the full PicWave package is capable of modelling other non-linear and active devices such as laser diodes and SOAs as discussed in Chapter 8. More information about PicWave can be found at www.photond.com/products/picwave.htm. In addition to researchers, scientists, and graduate students, this book will be of interest to industrial practitioners in the field of fabrication of fiber optic materials and devices. Raman Kashyap, Canada Research Chair holder on Future Photonics Systems, and Professor at École Polytechnique, University of Montréal since 2003, has researched optical fibers and devices for over 30 years. He pioneered the fabrication of FBGs and applications in telecommunications and photonics. - Provides an overview of Fiber Bragg Gratings (FBGs), from fundamentals to applications - Evaluates the advantages and disadvantages of particular applications, methods and techniques - Contains new chapters on sensing, femtosecond laser writing of FBGs and poling of glass and optical fibers - Includes a special version of the photonic simulator PicWave(tm), allowing the reader to make live simulations of many of the example devices presented in the book

Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of papers that originated as a Special Issue, focused on some recent advances related to fiber Bragg grating-based sensors and systems. Conventionally, this book can be divided into three parts: intelligent systems, new types of sensors, and original interrogators. The intelligent systems presented include evaluation of strain transition properties between cast-in FBGs and cast aluminum during uniaxial straining, multi-point strain measurements on a containment vessel, damage detection methods based on long-gauge FBG for highway bridges, evaluation of a coupled sequential approach for rotorcraft landing simulation, wearable hand modules and real-time tracking algorithms for measuring finger joint angles of different hand sizes, and glaze icing detection of 110 kV composite insulators. New types of sensors are reflected in multi-addressed fiber Bragg structures for microwave–photonic sensor systems, its applications in load-sensing wheel hub bearings, and more complex influence in problems of generation of vortex optical beams based on chiral fiber-optic periodic structures. Original interrogators include research in optical designs with curved detectors for FBG interrogation monitors; demonstration of a filterless, multi-point, and temperature-independent FBG dynamical demodulator using pulse-width modulation; and dual wavelength differential detection of FBG sensors with a pulsed DFB laser.
