“…Assuming that SMI operates in a low-feedback regime where the effect of multiple reflections in the external cavity is small, the interference signal detected by the photodetector (PD) with sinusoidal phase modulation φ(t) is given by [15][16][17] where I 0 denotes the unperturbed optical output power, φ(t) is the measured phase of the external cavity, m is the fringe visibility, n is the refractive index of air, L(t) is the length of the external cavity, and λ 0 is the central wavelength in vacuum. φ(t)=asin(2πf m t+β) is the sinusoidal phase modulation term, where a is the modulation depth, f m is the modulation frequency, and β is the initial phase.…”

Micro-displacement measurement based on self-mixing interference using a fiber laser system was demonstrated. The sinusoidal phase modulation technique was introduced into the fiber laser self-mixing interference measurement system to improve the measurement resolution. The phase could be demodulated by the Fourier analysis method. Error sources were evaluated in detail, and the system was experimentally applied to reconstruct the motion of a high-precision commercial piezoelectric ceramic transducer (PZT). The displacement measurement resolution was well beyond a half-wavelength. It provides a practical solution for displacement measurement based on all optical-fiber sensing applications with high precision.

“…17 A fiber-optic vibration sensor can typically be based on the modulation of the light properties in the optical fiber, such as intensity, phase, polarization state, and frequency, where these are (mainly) caused by externally applied vibration (and compensation for extraneous effects such as temperature can be included). The most common fiber-optic vibration sensors discussed in the literature are point, [18][19][20][21] quasi-distributed, 22 and distributed sensors. 23,24 Different (and often complementary) optical techniques can be employed for each of these.…”

An innovative vibration sensor based on a Fabry-Perot interferometer (FPI) using fiber Bragg grating (FBG) reflectors was demonstrated in this work. The sensor was designed to be compact and easy to fabricate, independent of temperature, to overcome limitations seen in previous designs, providing an effective correction for temperature effects in FBG-based FPI (FBG-FPI) sensors. A laser source with a peak wavelength of 1547.42 nm obtained from the FBG reflective peak was used to illuminate the FBG-FPI so that the light source was always within the FBG-FPI optimum wavelength operating range of 1547.15 to 1547.80 nm. The sensor was shown to capture a 3-kHz burst signal from a signal generator in 1-, 2-, and 3-Hz intervals. In addition, the work carried out has revealed that the sensor could be used to capture sinusoidal signals at frequencies up to 9 kHz, creating a performance comparable with many existing conventional piezoelectric sensors. Furthermore, the ability to operate regardless of any ambient temperature changes [from 26.5°C (room temperature) up to 80°C] opens the way to use such a sensor system over a wide range of engineering applications taking advantage of the next generation of FBG-based FPIs.

“…Up to now, fiber-optic vibration sensors mainly consist of point [ 11 , 12 , 13 , 14 ], quasi-distributed [ 15 ], and distributed sensors [ 16 , 17 ]. Several schemes of point sensors including fiber Bragg grating (FBG), Fabry–Pérot [ 18 , 19 ], self-mixing [ 20 ], and Doppler vibrometry [ 21 , 22 ] are deployed for vibration measurement.…”

Distributed fiber-optic vibration sensors receive extensive investigation and play a significant role in the sensor panorama. Optical parameters such as light intensity, phase, polarization state, or light frequency will change when external vibration is applied on the sensing fiber. In this paper, various technologies of distributed fiber-optic vibration sensing are reviewed, from interferometric sensing technology, such as Sagnac, Mach–Zehnder, and Michelson, to backscattering-based sensing technology, such as phase-sensitive optical time domain reflectometer, polarization-optical time domain reflectometer, optical frequency domain reflectometer, as well as some combinations of interferometric and backscattering-based techniques. Their operation principles are presented and recent research efforts are also included. Finally, the applications of distributed fiber-optic vibration sensors are summarized, which mainly include structural health monitoring and perimeter security, etc. Overall, distributed fiber-optic vibration sensors possess the advantages of large-scale monitoring, good concealment, excellent flexibility, and immunity to electromagnetic interference, and thus show considerable potential for a variety of practical applications.
