These sensors are deployed for measuring a wide variety of technical parameters, ranging from chemical composition to mechanical measurements such as strain & temperature sensing, liquid level monitoring, and so on. These sensors are robust, resistant to electromagnetic interference, highly sensitive, and lightweight. These sensors can be further bifurcated, based on their operation modes, into extrinsic and intrinsic.
The DFOS equipment manufacturers and service providers have undertaken considerable M&As in the recent-past to gain access to numerous technological patents in the DFOS application domain and enhance their service portfolios.
Based on applications, the market has been segmented into tempertaure sensing, acoustic/vibration sensing, and others. The temperature sensing segment is anticipated to dominate the distributed fiber optic sensors application arena (in terms of size) by 2025. The vibration/acoustic segment is anticipated to witness a significant growth, owing to its increasing adoption across the security application segment.
These sensors help in the generation of a continuous profile of temperature, acoustics, or strain conditions along the entire length of the fiber. Distributed fiber optic sensors enable high accuracy of detection over long distances. It provides critical data in various applications and serves as a cost-effective option for monitoring physical parameter sensing at multiple points in difficult operating conditions.
The temperature and acoustic/vibration segments are expected to witness steadiness in their growth and govern the market (in terms of growth rates) over the estimated time. However, factors, such as high initial capital investment (required to manufacture and deploy new DFOS technologies) may impede the market demand over the forecast period.
Acoustic sensor’s better sensitivity compared to the temperature sensors is likely to act as a major driver in its rapidly increasing penetration in power & utility, civil engineering verticals, and the oil & gas. The acoustic sensing market would grow at the significant rate predominantly on account of its complimentary role played as temperature sensor.
Based on technologies, the market has been segmented into Rayleigh effect, Brillouin scattering, Raman effect, interferometric, and Bragg Grating. The Raman effect-based technology segment is anticipated to dominate the market (in terms of size) by 2025. The Brillouin scattering segment is anticipated to witness a significant growth rate, due to its growing adoption. These sensors have unique operational abilities, over multiplexed or pointed fiber-optic sensors originated on inline Fabry-Perot resonator and fiber Bragg grating.
Rayleigh scattering is caused by the microscopic variations in the refractive index of the fiber core caused by the fluctuations in composition and density of the optical fiber. Rayleigh scattering based sensors are considered to be only set of sensors which has an equal amount of sensitivity to almost any kind of changes in physical parameters. In this scattering method, only scattering is used to track and reveal propagating effects, which helps in sensing the various physical parameters. This is one of the major reasons behind the Rayleigh scattering effect being used to measure almost all the physical parameters falling in the ambit of distributed fiber optic sensing.
The Raman scattering-based distributed fiber optic sensors are widely used in dynamic applications across the oil & gas and construction sector. Raman scattering is the utmost favored method, owing to its accuracy in measuring physical parameters and its characteristics of upholding a balance between the range to which it can sense physical parameters. The growing penetration of transportation infrastructure in developing economies, such as China and India, is attributable to the significant growth of the fiber optic sensing technology in the region.
The fiber optic sensors for temperature sensing application are principally used for power cable monitoring in the power and utility vertical and for pipeline and process monitoring purposes in the oil & gas vertical. Increasing demand for accuracy of distributed optical sensing coupled with data-based decision-making, is driving the market. Along with this, surging demand for structural health monitoring and related applications will also a play a major role in driving the market growth
Based on verticals, the market has been segmented into oil & gas, power & utility, safety & security, industrial, and civil engineering. The oil & gas vertical is anticipated to dominate the distributed fiber optic sensor application arena (in terms of size) by 2025. The safety & security segment is anticipated to witness a significant growth rate, owing to its growing adoption in dynamic sensing applications and paramount efficiency.
