“…Generally, a fiber optic sensor will consist of a source of light, sensing and transmission fiber, a photo detector, demodulator, processing and display optics [17]. Fiber optic sensor can be categorized into three groups [25]: interferometric sensors [78], distributed sensors [50] and grating-based sensors [43,74]. In SHM applications, the most popular are Extrinsic FOS: Extrinsic Fabry-Perot in- terferometric (EPFI - Fig.…”

The present paper is devoted to the discussion and review of the non-destructive testing methods mainly based on vibration and wave propagation. In the first part, the experimental methods of actuating and analyzing the signal (vibration) are discussed.The piezoelectric elements, fiber optic sensors and Laser Scanning Doppler Vibrometer (SLDV) method are described. Effective detecting of the flaws needs very accurate theoretical models. Thus, the numerical methods, e.g. finite element, spectral element method and numerical models of the flaws in isotropic and composite materials are presented. Moreover, the detection of the damage in structures, which are subjected to cyclic or static loads, is based on the analyzing of the change in natural frequency of the whole structure, the change of internal impedance of the material and the change in guided waves propagating through the investigated structure. All these cases are characterized in detail. At the end of this paper, several applications of the structural health monitoring systems in machine design and operation are presented.

“…An ultrasonic wave causes a refractive index change via the strain-optic effect. Supposing it brings no shear strain and the fiber is isotropic and homogeneous, the refractive index relates to the ultrasonic effect as follows [4]:…”

“…However, optical fiber sensors offer significant advantages over their electrical counterparts in terms of improved reliability and reduced physical profile. The most significant performance is their immunity to electromagnetic interference, which enables applications under harsh environment [4]. In recent years, FBG has become an attractive candidate for ultrasonic wave detection, because it can be easily embedded in the structure of the body being monitored and is ideal for multiplexing [5,6].…”

In recent years, fiber Bragg grating (FBG), for the well-known advantages over other fiber optic sensors, has attracted more attention in ultrasonic inspection for structure health monitoring (SHM). Spectrum shift of FBG to ultrasonic wave is caused by the refractive index profile changing along the FBG, which can be attributed to nonuniform perturbation caused by strain-optic and geometric effects of ultrasonic wave. Response of FBG to the above two effects was analyzed firstly by the V-I transmission matrix model, showing high computing efficiency. Based on this model, spectra response of FBG under changing ultrasonic frequencies was simulated and discussed. In experiment, the system was able to detect a wideband ultrasonic wave ranging from 15 to 1380 kHz. These results would provide a guideline for an FBGbased acoustic detection system design in a specific ultrasonic frequency.

“…Moreover, the lack of FBG sensing and interrogation standards, means the technology has only significantly progressed in niche applications, such as structural health monitoring [6,7] and protection of industrial assets [8], which will not be covered in detail in this review article. An extensive review of fibre based opto-acoustic sensors used in structural health monitoring is given in [9] and a review of optical fibre sensors specifically for physical security applications is provided in [10].…”
