“…При необходимости увеличения или уменьшения чувствительности применяются различные покрытия ОВ [18,19]. Отсутствие механических и токопроводящих частей, низкие массогабаритные параметры и возможность мультиплексирования большого количества датчиков на одном оптическом волокне привели к широкому развитию измерительных систем на основе ВБР, годовой оборот рынка которых исчисляется миллиардами долларов [1]. Принцип применения ВБР в качестве ЧЭ датчика ультразвуковых (УЗ) воздействий состоит в следующем: длина волны λ 0 источника оптического излучения (ИИ) с узким спектром выбирается таким образом, чтобы она попадала в середину линейной области (рис.…”

Subject of Research. This paper presents the results of an experimental study on the possibility of applying single fiber Bragg gratings as sensitive elements for detecting ultrasonic impacts in gaseous or liquid media and at placing fiber Bragg gratings into various materials and structures for their status monitoring. Method. During the experiment, an ultrasonic impact with a fundamental frequency of 65 kHz was alternately turned on two sensitive elements based on two fiber Bragg gratings with different parameters: the physical grating length, reflection coefficient, and slope of the linear part of spectral characteristics. Comparative analysis of the obtained data with data from the reference piezoelectric ultrasonic sensor was performed. The results were evaluated in the frequency domain, at the range up to 200 kHz. The three first harmonics of the signal were studied: 65, 130 and 195 kHz. The signal-to-noise ratio for each sensor element and the ratio of signal values obtained from various sensor elements were evaluated. Main Results. The measurement setup was created on the basis of a small-sized tunable VCSEL and FPGA. It is shown that single fiber Bragg gratings are suitable for creation of sensitive elements for ultrasonic sensors and have values of sensitivity and dynamic range comparable to piezoelectric sensors. The range of detected frequencies was theoretically estimated and the assessment of the FBG parameters effect on the sensor sensitivity to ultrasonic action was performed. The ratios of the signals measured by the Bragg grating with a slope of the spectral characteristics equal to 142 1/nm and a reflection coefficient equal to 100%, to the signals from the grating with a slope of 44 1/nm and a reflection of 40% are equal to 5.8, 3.8, 7.1 for 65, 130 and 195 kHz, respectively. The ratios of the signals measured by the reference piezoelectric sensor to the signals measured by Bragg grating with a slope of the spectral characteristics equal to 142 1/nm and a reflection coefficient of 100% are 3.8, 6.2, 7.7 for 65, 130 and 195 kHz, respectively. Practical Relevance. The results of this study show the possibility of applying fiber Bragg gratings as the sensitive elements of threshold and measuring ultrasonic sensors for the placement in the volume and on the surface of the materials under study. The features and advantages of fiber-optic measuring systems provide the ease of installation for the arrays of sensors in the material or structure under research during production, insensitivity to external electromagnetic interference and the possibility of multiplexing a large number of sensitive elements on a single optical fiber.

“…In fact, fiber based MMIs are a simple device that comprises a single-mode-multimode-single-mode structure (SMS), which allows easy and compact implementation. On the other hand fiber Bragg gratings (FBGs) are a common sensing device widely used in sensing applications [20]. The potential of combining these fiber structures has already been subject of study in literature [11-16, 18, 21].…”

In this paper an intensity liquid level sensor based on a single-mode—no-core—single-mode (SMS) fiber structure together with a Bragg grating inscribed in the later single mode fiber is proposed. As the no-core fiber is sensitive to the external refractive index, the SMS spectral response will be shifted related to the length of no-core fiber that is immersed in a liquid. By positioning the FBG central wavelength at the spectral region of the SMS edge filter, it is possible to measure the liquid level using the reflected FBG peak power through an intensity-based approach. The sensor is also self-referenced using the peak power of another FBG that is placed before and far from the sensing part. The temperature error analysis was also studied revealing that the sensor can operate in environments where the temperature changes are minimal. The possibility to use a second setup that makes the whole device temperature insensitive is also discussed.

“…Fibre Bragg gratings (FBGs) have an outstanding position among optical fibre sensors, due to their multiplexation capability and relatively easy monitoring [28,29], including flexibility for wavelength shift determination or damage detection by post-processing signals in the case of reflected spectrum modification by nonuniform strain distribution in the piece.…”

Composites have added new dimensions to the design and construction of buildings and structures. One of the wider spread composite applications in the construction industry is composite beams or pillars, which can be manufactured through pultrusion processes. These types of construction elements are usually used to withstand the weight of large loads, so their integrity must be guaranteed. Due to optical sensors’ advantages over their electrical counterparts—small sizes, low weight, non-conductive, and immunity to electromagnetic interference—and FBGs having an outstanding position among optical fibre sensors—due to their multiplexation capability and relatively easy monitoring—in this study, we propose the integration of FBG sensors for the observation and analysis of the integrity of structures made with composite beams over time. The validation test results showed the successful embedding integration of FBG-based fibre optical sensors in an FRP pultrusion beam and strain transmission up to 7500 µɛ from the composite test piece to the sensor. Additionally, we were able to anticipate the piece failure by the FBG spectrum deformation.
