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.
