“…These areas can be combined into two large groups: objects of great length (pipelines, railways, highways) and medium-range structures requiring permanent monitoring activity (composite materials in aircrafts). For the latter, DAS have replaced a large number of electrical point sensors that are difficult to implement due to the huge number of required electrical wires [ 78 , 79 ]. The following paragraphs will cover the main results obtained in the engineering applications over the past few years.…”

This work presents a detailed review of the development of distributed acoustic sensors (DAS) and their newest scientific applications. It covers most areas of human activities, such as the engineering, material, and humanitarian sciences, geophysics, culture, biology, and applied mechanics. It also provides the theoretical basis for most well-known DAS techniques and unveils the features that characterize each particular group of applications. After providing a summary of research achievements, the paper develops an initial perspective of the future work and determines the most promising DAS technologies that should be improved.

“…However, as for the very-low-frequency band, they only provided the theoretical prediction between 30 Hz and 100 Hz due to the limitations of the underwater acoustic projector [71]. Recently, researchers in Russia have reported a hydrophone used in their towed array, but the acoustic pressure responsivity is not a flat pattern from 20 Hz to 495 Hz [72]. In contrast, a report from China has shown that the acoustic sensitivity is about 115 dB re Hz/Pa between 10 Hz and 10 kHz for their DFB FL-style FOH, which has improved the very-low-frequency detection ability compared with other designs [73].…”

“…It was reported by an Indian group that their demonstration possesses an outer diameter of 32 mm [99]. The researchers from Russia reported an interferometric towed linear array with an outer diameter of 20 mm, which is a real challenge for the interferometric scheme [72]. Almost simultaneously, Chinese researchers reported a sea trial using a 16-element DFB-FL based towed linear array with a diameter of only 12 mm, and the towed noise of the array was 69 dB re mPa/Hz 1/2 @1 kHz [100].…”

Fiber-optic hydrophone (FOH) is a significant type of acoustic sensor, which can be used in both military and civilian fields such as underwater target detection, oil and natural gas prospecting, and earthquake inspection. The recent progress of FOH is introduced from five aspects, including large-scale FOH array, very-low-frequency detection, fiber-optic vector hydrophone (FOVH), towed linear array, and deep-sea and long-haul transmission. The above five aspects indicate the future development trends in the FOH research field, and they also provide a guideline for the practical applications of FOH as well as its array.

“…Nowadays, many tasks can be solved in science and technics with the help of FOSs. They are useful for measuring deformation [ 9 ], temperature [ 10 , 11 , 12 ], vibration [ 13 ], concentration of substances [ 14 ], rotation speed [ 15 ], refractive index [ 16 ], pressure [ 17 ], liquid level [ 18 ], acceleration [ 19 ], acoustics [ 20 , 21 , 22 ], and other parameters [ 2 , 23 , 24 , 25 ]. Additionally, new types of fiber promise to open new opportunities for such monitoring devices [ 26 , 27 ].…”

In this study, an experimental study of the burning rate of solid fuel in a model solid propellant rocket motor (SRM) E-5-0 was conducted using a non-invasive control method with fiber-optic sensors (FOSs). Three sensors based on the Mach–Zehnder interferometer (MZI), fixed on the SRM E-5-0, recorded the vibration signal during the entire cycle of solid fuel burning. The results showed that, when using MZI sensors, the non-invasive control of solid fuel burnout is made possible both by recording the time of arrival of the combustion front to the sensor and by analyzing the peaks on the spectrogram of the recorded FOS signal. The main mode of acoustic vibrations of the chamber of the model SRM is longitudinal, and it changes with time, depending on the chamber length. Longitudinal modes of the combustion chamber were detected by MZI only after the combustion front passed its fixing point, and the microphone was unable to register them at all. The results showed that the combustion rate was practically constant after the first second, which was confirmed by the graph of the pressure versus time at the nozzle exit.
