Distributed Acoustic Sensing (DAS) and its applications

DAS and its applicationsIn southwest Iceland, there is a fiber optic cable that connects two geothermal power plants. It is used as every casual fiber optic cable for data transmitting. However, in 2015 a research team decided to apply it for detecting seismic waves of earthquakes, so they could draw a map of the underground features including geological faults. And distributed acoustic sensing (DAS) made it possible.

Scientists made their discovery thanks to distributed acoustic sensing (DAS). This technique measures any tiny changes to the phase of fiber optic laser pulses that reflect from many points on fiber optics. The thing is an acoustic or seismic wave stretches and compresses fiber optics when it passes through the ground where the fiber optic is attached. DAS systems can provide the necessary information at a reasonable cost. Moreover, the usual seismometers couldn’t reach such kind of information.

In fact, Iceland is not the first country where the distributed acoustic sensing (DAS) technology was applied. Before that, fiber optic cables were produced in other seismic regions, for example, in the USA. The precise information on earthquakes’ location, nearby faults was got thanks to the fiber optics both on the seabed and on land. Scientists consider that by using a million kilometers of fiber optic cable around the world, we can broaden quake monitoring thanks to the network of seismometers with fiber optic sensors.

Distributed acoustic sensing (DAS) has been previously applied mostly in the fossil-fuels industry. The sensing technology helped to monitor boreholes and image deposits of oil and gas. Nowadays, it has many other applications for extracting data from vibration in the ground. Distributed acoustic sensing can even shed some light on global warming by studying the glaciers’ movements in the Antarctic and Alaska.

Besides earthquakes, researchers proved that they can use DAS systems for studying other natural hazards. The research team from Italy showed that they can detect the strain changes connected to the volcanic phenomena which include explosions. They also discovered seismic waves slowing through presumed fault zones on the volcano.

In the meantime, scientists from Japan demonstrated that DAS technology can monitor submarine volcanoes. The researchers measured the signals from the fiber optic cable on the seafloor. They found out that fiber optic sensors could produce coherent measurements that are needed for underwater eruptions’ recording.

Distributed sensing is an effective instrument that provides us with a lot of data that we can’t observe with the naked eye. Considering how widely fiber optic lines are used, distributed acoustic sensing (DAS) can give many possibilities to scientists and society.

Fiber Optic Technology and its recent advances

Fiber Optic Technology advancesDuring the last 60 years, fiber optic technology has been applied to improve the efficiency of developed systems in various spheres like medicine, vehicles, and other industries. Modern fiber optic solutions expand the abilities by implementing levels of data and sensing technology in the energy, medical field, and even aerospace. There are various fiber optic solutions that help researchers improve their development and make new discoveries in science.

Intrinsic and extrinsic fiber optic sensors are two wide categories of fiber optic sensors. Extrinsic fiber optic sensors utilize the fiber to manage the light to a sensing region. Then the optical signal is modulated in another environment. Talking about the intrinsic fiber optic sensors, the light remains within the waveguide. So it measures the influence of the optical fiber signal.

Intrinsic fiber optic sensor technology, where the fiber optic sensor is the fiber optic cable itself, has improved significantly during recent years. There are two main technologies connected to intrinsic fiber optic sensors: scattering and FBG. FBG methods can be fully distributed or have many sensing points. With the help of FBG sensors, scientists can define the changes by getting precise measurements. Scattering techniques depend on natural imperfections occurring in the fiber optic cable. The FBGs have a high signal-to-noise ratio in comparison with scattering techniques.

Both scattering and FBGs use different demodulation techniques. Scattering techniques get the information by observing changes in naturally back-scattering patterns. For FBG based technology, wavelength division multiplexing is the most prevalent demodulation technique. However, in certain circumstances, optical frequency domain reflectometry can become the most useful method.

Wavelength division multiplexing is able to spread to large distances and get the data rapidly. This technology can also support multiple fiber Bragg gratings on a fiber. It observes critical points more than the whole field of the data. That is why it is mostly applied in automobile crash testing as a monitoring instrument.

The scattering techniques can cover long distances and give a distributed profile of the data. They obtain information all over the entire fiber optic cable. Many systems on the market measure temperature or acoustics and are called Distributed Temperature Sensing (DTS) or Distributed Acoustic Sensing (DAS). These techniques are usually applied in monitoring a pipeline for tampering, for example, where there is no need for high-speed acquisition.

Optical frequency domain reflectometry is another demodulation technique that is mostly applied with FBG sensors where fiber Bragg gratings are placed really close and create a fully distributed sensing fiber. It has many advantages like the combination of high spatial resolution, a bunch of fiber optic sensors, a quick refresh rate, and a full distribution set. Apart from distributed sensing of a strain and temperature, this technology allows defining 2D deflection, liquid level, magnetic fields, etc.

Nowadays, thanks to fiber optic technology, scientists have an opportunity to solve any problems in their designs by using fiber optic systems. And there are still many possibilities for fiber optic technology in the future.

FBG pressure sensors detect the smallest changes

FBG sensors for pressure measurementA group of scientists from China has designed a very sensitive tiny fiber optic sensor for the measurement of the slightest pressure changes. Such FBG pressure sensors are suitable for medical applications. Herewith, they do not have numerous disadvantages of silica-based optical fibers.

According to scientists, such a fiber sensor is extremely sensitive, and it allows for measuring lung pressure even while breathing. The thing is that pressure changes in the lungs are very small and difficult to be detected. The operating principle of FBG pressure sensors is based on a fiber Bragg grating (FBG) inscribed into an optical fiber.

It should be noted that the optical fiber used is made of a new polymer. The pressure sensor detects the slightest pressure changes of 2 kilopascals. The biocompatibility of these fiber optic sensors makes them suitable for medical applications. Additionally, the fiber sensors are chemically inert, herewith they are not sensitive to moisture.

The scientists plan to use FBG pressure sensors to control different parameters that contain pressure, temperature, and strain. Moreover, numerous modern fiber sensors use FBG technology, “ tiny periodic microstructures that can be inscribed onto a fiber.” 

FBG sensors made of conventional silica-based fibers have several disadvantages for medicine. They are not convenient for long-term use in the body because these optical fibers are relatively hard and very frangible. Moreover, most FBG sensors made of silica perform limited sensitivity to the slightest pressure changes.

Compared to silica sensors, there are polymer fiber optic sensors. However, they absorb water. This is the main reason why scientists create advanced polymer optical fiber to solve the current problems. Novel FBG pressure sensors can be applied in aqueous environments.

Also, such material offers a higher light shift in response to a pressure change. The production of these FBG sensors becomes easier because it doesn’t require the use of dopants. Thus, scientists produce optical fibers with good reproducibility. 

The FBG pressure sensors have been already tested by comparing their performance with the standard polymer counterpart. Herewith, novel fiber sensors provide a linear, repeatable response.  They can be employed for low-pressure measurement up to 50 kilopascals above or below atmospheric pressure with a resolution of 2.0 kilopascals. 

Finally, these FBG sensors demonstrate higher sensitivity (80% higher than standard polymer-based sensors). Their promising applications include the operation not only in medical and high-altitude environments but also in gaseous containers.

FBG Sensors for power plants

FBG Sensors for power plantsNowadays researchers tend to use fusion as a safe energy source at power plants. Nevertheless, this process is dangerous. It requires reliable fiber optic technology for structural health monitoring at power plants. Novel fiber optic sensors offer robust operation in the harsh conditions of a commercial fusion power plant.

To be more precise, these fiber sensors provide temperature sensing applying optical fibers with written fiber Bragg gratings (FBGs). The FBG operating principle is based on broadband light that is directed on it. Although most of the light goes through, one wavelength is reflected. Herewith, the reflected wavelength changes with both temperature and strain.

Therefore, the installation of several fiber Bragg gratings enables performing independent temperature sensing of each location. Standard FBGs are widely used in various industries for strain and temperature sensing. Herewith, compact superconducting cables use these optical fibers based on fiber optic technology.

Novel FBG sensors can maintain “the intense electrical, mechanical, and electromagnetic stresses of a fusion magnet’s environment.” The novel fiber optic technology supposes ultra-long fiber Bragg gratings of 9-millimeter located 1 mm apart. The FBG sensors operate as conventional long quasi-continuous systems.

Compared to standard systems, FBG sensors include such benefits as long grating length (meters instead of millimeters). Ultra-long FBGs allow for sensing simultaneously occurring temperature changes along their entire length. Thus, it is possible to determine fastly temperature variation, irrespective of the location of the heat source.

Additionally, it is possible to combine ultra-long FBGs and traditional FBGs to produce both spatial and temporal resolution. The fiber optic technology has been developed by a team of researchers from Switzerland. According to them, such a combination can be used on bigger cables.

These FBG sensors detect quickly and accurately even the smallest temperature changes under realistic operation conditions. Moreover, they demonstrate a better signal-to-noise ratio thanks to their high level of sensitivity and the opportunity to adjust the optical fiber response.

Thus, the fiber optic sensors locate quench events tens of seconds faster than voltage taps. Herewith, the application of FBG sensors for HTS magnets quenches detection is very potential. It allows for overcoming the current problem of  HTS coils from damage during quenches.

Finally, such a fiber optic technology plays a crucial role in compact fusion processes, where practical, high-field, high-temperature superconducting magnets are important. FBG sensors are still under development and need some improvements to be used in new applications.

Distributed Temperature Sensing (DTS) measures moisture

DTS for moisture estimationPassive distributed temperature sensing (DTS) helps to improve the measurement of moisture content and temperature increase. The DTS technology has been already tested in China to prove the opportunities provided by this technique. Therefore, distributed temperature sensors are very promising for agriculture.

Several land conditions include bare soil, plastic mulch, plastic mulch covered with potatoes, and plastic much covered with maize. Land moisture plays a crucial role in influencing grain yield. Nevertheless, distributed temperature sensing is not suitable for the last type of land.

The thing is that several techniques allow for determining soil moisture content. Distributed sensing systems include point, ground, and regional types. Herewith, point fiber optic sensors consist of “oven-drying, neutron scattering, electrical impedance, time-domain reflectometry (TDR), frequency domain reflectometry (FDR), tensiometer, and thermal probe techniques.”

Conventional fiber sensors offer benefits of high precision and reliability but most of them are limited to a specific area. This is the main reason why it is difficult to determine accurately the overall ground moisture condition, especially in places where soil moisture distribution is discontinuous.

Thus, scientists have suggested applying distributed temperature sensing (DTS). DTS technology allows for estimating agricultural soil moisture, herewith, the distance of measurement can achieve several tens of kilometers. The operating principle of distributed temperature sensors is based on the heating of optical cables. When the temperature increases, the soil moisture can be estimated.

The DTS technology is not new and it quickly found the application in moisture measurement. According to this technique, it is possible to measure in situ soil moisture by employing analytical or semi-empirical models. Nevertheless, firstly it is necessary to calculate the thermal conductivity of the soil.

Compared to traditional techniques that have limitations, distributed temperature sensing allows for overcoming them. DTS estimates the temperature response of soil, therefore, measures soil moisture based on the data obtained by fiber optic sensors. Nonetheless, the proposed technique has several disadvantages.

Various weather conditions can influence the heat transfer way in the soil and the data obtained by distributed temperature sensors will be inaccurate. Additionally, boundary conditions and even time change periods also influence the precision. Finally, the standard algorithm is very difficult for application in practice.

Distributed fiber optic sensors: common applications

FBG sensors and common applicationsCommon communication channels apply fibers in fiber optic sensors where laser beam light passes along haul distances. These fiber sensors allow for determining, controlling, and measuring external parameters in a distributed format. Herewith, the optical fiber in a fiber optic system operates both as a distributed transducer and optical channel.

To be more precise, the fiber optic sensors measure various changes on specific parameters along with the transducer. Such factors as the dynamic range and the spatial resolution play a crucial role in distributed sensing but still have to be improved. The operating principle of fiber optic systems is based on “the incident light wave that produces acoustic waves through the electrostriction effect. It induces a periodic modulation of the refractive index of material that evokes a light-backscattering like a fiber Bragg grating of FBGs.”

It should be noted that a fiber sensor or sensing system is a tool that determines, measures physical or chemical parameters. Herewith, in the case of light use in such systems, this is a photonic or optical sensor. The fiber optic sensors, in turn, consist of optical fibers and the fiber optic technology around them.

Distributed fiber optic sensors detect and measure physical factors by Brillouin scattering of light in optical fibers. Brillouin scattering advances the development of precise distributed fiber optic systems. Additionally, these fiber sensors enable to measure specific variables.

Distributed sensing systems are very promising for structural health monitoring. The following parameters can be detected: strain and temperature, acoustic waves, and others. Moreover, these fiber optic sensors maintain severe environments and offer noise electromagnetic immunity, durability, and reliability.

The most common application of fiber sensors based on the Brillouin sensing technique includes laboratory implementation. Nevertheless, their applications are not limited to labs only. Distributed fiber optic sensors are widely used in such fields as:

  • The civil infrastructure where distributed sensing systems detects variables in bridges, railways, and land monitoring;
  •  Bridges and monitoring where compact fiber sensors promote accurate diagnostic load test;
  • Geotechnical structures monitoring for measuring and controlling of the stress distribution;
  • Pipelines monitoring by distributed fiber optic sensors in real-time for early warning of liquid and gas pipes;
  • Monitoring of some materials and structures, for instance, competition yachts or experimental vehicles.

FBG sensors for temperature and pressure measurement

FBG sensors for temperature and pressureNowadays fiber optic solutions play a crucial role in information technology. Fiber optic technology promotes the development of advanced fiber optic sensors. These fiber sensors offer numerous benefits that make them very attractive. The benefits include “durability, flexibility, biocompatibility, high sensitivity, and electromagnetic interference immunity.”

The applications of fiber optic sensors consist of numerous fields. They are widely used in medicine, environmental protection, industrial production, and structural health monitoring. Herewith, different types of fiber sensors allow for measuring various physical and chemical parameters. For instance, they sense temperature, acoustic, pressure, humidity, and others.

The production of distributed sensing systems requires different types of fibers. The following types are the most popular: photonic crystal, polarization-maintaining, double-core, sapphire optical fibers, etc. It should be noted that various fiber optic sensors use various measurement principles. Additionally, fiber Bragg gratings (FBGs) – the most popular measurement principle.

FBG sensors can also perform multi-parameter measurements to meet the practical demands of scientists. Thus, a team of researchers has demonstrated a cascaded multi-mode FBG sensor that performs the dual-parameter measurement. They apply optical fiber with several modes to create a distributed sensing system. Moreover, the FBG sensors measure the Brillouin frequency shift for temperature and strain sensing.

To be more precise, these FBG sensors have a hybrid structure (FBGs and FPI) with a nano-silica diaphragm on the tip. Besides, the total length of the fiber sensor is less than a human hair. These FBG sensors determine both environmental temperature and pressure. Therefore, such a fiber optic solution is highly promising in specific applications in severe environments.

Finally, the hybrid fiber optic sensor has been already produced and even tested. The distributed sensing system includes an FPI with a silica diaphragm. Also, fiber optic technology applies the femtosecond laser inscription technique and arc discharge methods. These FBG sensors demonstrate a high level of pressure and temperature sensitivity.

Additionally, the fiber optic sensor has an ultra-low level of cross sensitivities. “The temperature-induced error of the pressure measurement was –1.4286 kPa/ and ℃ pressure-induced error of the temperature measurement was ~0℃/MPa.” The mentioned-above benefits of FBG sensors make them perfect for numerous fields of applications.

Fiber optic sensors for plant detection

FBG sensors for plant detectionA novel fiber optic technology developed by researchers from Singapore becomes the basis for a novel fiber sensor for plant detection. The fiber optic sensors perform both detection and real-time monitoring of arsenic levels in underground environments. Such monitoring by distributed sensing systems is very important because it shows the presence and quantity of the metal.

The operating principle of this fiber optic system is based on the plantation of fiber sensors into plant tissue. Thus, fiber optic technology allows for detecting arsenic as low as 0.2 parts per billion. Compact and low-cost electronics records data. To be more precise, the combination of fiber optic sensors and plants operate as a fully functional environmental detection system.

It should be noted that such fiber optic systems can be useful in environmental monitoring and agriculture. The thing is that arsenic is a widespread contaminant in most crops, so its detection is crucial for structural health monitoring. Additionally, it is dangerous for human health because it causes cardiovascular disease and even cancers.

It is possible to tune selectively these fiber optic sensors to detect particular arsenic quantities. Herewith, the nanotubes used in fiber sensors do not photobleach, therefore, they have stable emission over time. These fiber optic systems are safe for plants in which they are installed. The technology has been already tested and demonstrated great improvement in time- and equipment-intensive sampling techniques.

“The newly demonstrated technique benefits from the natural ability of plants to extract analytes from their roots and move them throughout their body.” The fiber optic sensor embedded in the living plant presents perfect operation. The researchers use a camera in the fiber optic system to obtain real-time imaging and analysis. Herewith, this fiber sensor can be controlled with compact low-cost electronics.

The tests have been already carried out on spinach and rice, as well as a species of fern. Some properties of fern species promote optimizing the fiber optic sensors to locate extremely low concentrations of arsenic. Compared to the novel fiber system, conventional sensors have a 10 ppb limit.

Thus, fiber optic technology enables the development of more resistant crops to toxic contaminants. The researchers claim that it is possible to transform any living plants into fiber sensors for arsenic detection. Now it is planned to create a compact, portable fiber optic system to control the fluorescence of the sensors within the plants. Finally, novel fiber optic sensors are highly reliable no only in labs but also under field conditions.

Fiber optic sensors for biological liquids

FBG sensors for biological liquidsA team of scientists from Israel and Russia has developed a novel, straightforward, and low-cost fiber optic technology. It allows for the testing of liquid biological samples. Herewith, the developed fiber optic system is very promising in clinical settings, containing real-time testing during surgery.

To be more precise, fiber optic sensors are widely applied in the healthcare system for real-time diagnostic testing for biological samples. The fiber sensors offer a high level of sensitivity, however, usually “that sensitivity comes at a cost in terms of time and resources.”

Therefore, scientists tend to create simple, inexpensive fiber optic sensors as a more efficient alternative. It should be noted that they pay careful attention to the optical dispersion of the refractive index of a sample. The thing is that this process of the fiber optic system operates as a fingerprint of sorts that controls the changes in its composition.

Thus, the team has presented the concept of multispectral fiber optic sensing for liquid biological samples in both static and real-time modes. Herewith, fiber optic technology is accurate, robust, and highly sensitive to impurities in the sample. These fiber optic sensors will be helpful for diagnostic applications and real-time simulations of different biological processes.

The fiber sensors include hollow-core microstructured optical fibers. It is a specific type of optical fiber that keeps light inside a hollow core of the fiber optic system surrounded by microstructured cladding. Liquid passes through champers of fiber sensors, and the team registers spectral shifts of maxima and minima in the transmission spectrum.

These signals show the chemical composition of the sample. Additionally, the fiber optic sensors do not require an external cavity or interferometer. This is the main reason why fiber optic sensing is straightforward and virtually cheap to create. Such fiber optic technology has been already tested by scientists.

The fiber sensors test the concentration of bovine serum albumin, generally applied in such experiments, dissolved in water and phosphate-buffered saline solution. The fiber optic system demonstrated a resolution similar to the accuracy of standard albumin tests and complied with clinical requirements.

The potential application of these fiber optic sensors includes the analysis of biomarkers of various types. It is necessary to test the fiber sensors on other bioanalytics and then modify them to enhance specificity. The fiber optic technology opens new opportunities ina fast, inexpensive and robust analysis of blood and other bodily liquids in real-time.

Fiber optic sensors for ammonia detection

FBG sensors for ammonia detectionA team of scientists from Denmark in a collaboration with chemical engineers has presented novel accurate fiber optic sensors. They allow for significantly decreasing the level of air pollution. The operating principle of this fiber sensor is based on modern telecom technology. It helps to detect and measure ammonia in the atmosphere by the sensing system, a laser, and hollow-core optical fibers.

To be more precise, the fiber optic system provides continuous ammonia monitoring for agricultural application. Additionally, the fiber optic sensor can be created at a pretty low cost. The benefits of fiber sensors such as compact size, high reliability, and low cost meet the requirements of a portable system for detecting ammonia.

It should be noted that such a fiber optic technology is still under development. The thing is that the sensitivity of the fiber sensor requires improvements, which scientists try to perform. Even though the main purpose of the new sensing system is ammonia detection, it is possible to use fiber optic sensors for the detection of other gases, for instance, greenhouse gases. 

Moreover, fiber optic technology operates as a part of one agricultural project. In this project, scientists develop new techniques and technology to measure and reduce air pollution from the agricultural sector. Nowadays the agricultural sector is considered to be the main contributor to air pollution (mainly caused by ammonia). Therefore, agricultural pollution is the biggest environmental issue that requires efficient fiber sensors.

The thing is that now ammonia emissions are challenging to measure at the farm level. Compared to novel fiber optic sensors, traditional systems for ammonia detection have a high cost. Fiber optic technology is very promising with great prospects for agriculture. “The ability to continuously and cost-effectively track the development in ammonia emissions from agriculture offers completely new opportunities for the industry to experiment on decreasing the emissions.”

Scientists claim that there are already established figures considering air pollution from agriculture. Nevertheless, the future potential of fiber optic sensors may greatly transform the detection way of ammonia caused by agricultural farms. The new fiber optic technology promotes farmers to control their emissions continuously.

Finally, precise monitoring of ammonia emissions provided by sensing systems makes streamline operations far better. Thus, fiber sensors lead to emissions-based regulations that help reduce the environmental impact of agriculture. The development of these fiber optic sensors will continue until the next year.
