Fiber Bragg Grating Based Sensors And Systems

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.

The book is an exciting source of information for individuals interested in learning about and marketing sensors. The book focuses on scientific and commercial advances in Fiber Bragg Grating (FBG) sensor technology since its discovery over 30 years ago.

This book presents the basic principles of optical sensor technology in line with the tremendous development in the concept of optical fibers. In the first four chapters, the book discusses the basic principles of optical sensor technology in a simplified manner, making it suitable for all levels of study and research. The seven remaining chapters are concerned with the practical applications of optical sensor technology in all fields such as oil and gas, civil engineering, medical and military fields and harsh environments.

Optical Fiber Sensor Technology, Advanced Applications - Bragg Gratings and Distributed Sensors, builds upon the foundations of the subject in the preceding four volumes of this series, concentrating as they do upon both applications and the technology of advanced optical fiber sensors. Previous volumes have covered the fundamentals of the field, devices and systems and chemical and environmental monitoring. This volume deals with a range of highly topical sensor devices and commercial systems, with considerable emphasis upon one of the most important areas, Bragg gratings in fibers, their fabrication and applications in advanced sensor systems and the principles and use of distributed fiber optic sensors. The volume is well illustrated and referenced, pointing to hundreds of key publications accessible in the open literature. It draws upon a group of authors with an international reputation for their work in the area, carefully edited into a coherent and logical text by the editors, based on their considerable experience in the field. This book series will provide an invaluable source for researchers, engineers and advanced students in the field of optical fibers, optoelectronics and measurement and sensing.
