“…In addition, optical fibre sensors respond to a change in optical intensity, phase, frequency, polarization, wavelength, or mode when exposed to environmental effects [17]. Many types of optical fibre sensors have been reported in the literature, including Bragg Grating, distributed sensing (BOTDA, OTDR), Fabry-Perot Interferometry, Long gauge Grating, SOFO, and so on.…”

Fibre-Reinforced Polymer (FRP) composites have been widely used in civil engineering for the past two decades. This paper presents an overview of the smart components and structures based on FRP. The basic principles of intelligent structures made of FRP and Optical fibre sensors are introduced. Some significant up-to-date smart elements used as reinforcing and health monitoring structures are also described in detail. Moreover, certain applications of smart FRP systems in civil engineering are briefly mentioned. Smart bars based on FRP are found to be very useful and could replace conventional steel. In addition, FRP-OF-OFBG is one of the most advanced techniques for local and global monitoring. However, interface strain for externally reinforcing systems requires specific characteristics to overcome debonding effects. Finally, analysis of the problems of existing applications based on carbon fibre composites are highlighted, followed by a description of some possibilities of new designs of smart FRPs.

Recent developments in fiber-optic sensing have involved booming research in the design and manufacturing of novel micro-structured optical fiber devices. From the conventional tapered fiber architectures to the novel micro-machined devices by advanced laser systems, thousands of micro-structured fiber-optic sensors have been proposed and fabricated for applications in measuring temperature, strain, refractive index (RI), electric current, displacement, bending, acceleration, force, rotation, acoustic, and magnetic field. The renowned and unparalleled merits of sensors-based micro-machined optical fibers including small footprint, light weight, immunity to electromagnetic interferences, durability to harsh environment, capability of remote control, and flexibility of directly embedding into the structured system have placed them in highly demand for practical use in diverse industries. With the rapid advancement in micro-technology, micro-structured fiber sensors have benefitted from the trends of possessing high performance, versatilities and spatial miniaturization. Here, we comprehensively review the recent progress in the micro-structured fiber-optic sensors with a variety of architectures regarding their fabrications, waveguide properties and sensing applications.

“…Interferometric fiber-optic sensors have shown high sensitivity and large dynamic range in their response to applied strain, temperature, and electric and magnetic fields [1,2]. The output of an interferometric sensor is a nonlinear and cosinusoidal function of the phase difference between the optical waveguides in the two arms.…”

A simple but reliable measurement method for the dynamic phase shift in a passive homodyne interferometric fiber-optic sensor is proposed. The amplitude of the dynamic phase shift is calculated directly from the photodetector output. A Mach-Zehnder interferometer with a PZT, which is used to generate the simulation signal, is constructed. The experimental results obtained using this simple method are well in agreement with the results given by the standard phase generated carrier (PGC) method, which shows the validity of the results. This new method has the advantages of simplicity of operation, no active element in the sensing head, no modulation to the laser, large dynamic range and working bandwidth, etc. It can be used for the dynamic phase shift measurement of various interferometric fiber-optic sensors.
