10-Year Forecast – Fiber Optic Sensors

According to ElectroniCast, the combined use of Distributed and Point fiber optics sensors are forecast to reach $5.98 Billion in 2026…
 ElectroniCast Consultants, a leading market/technology forecast consultancy, today announced the release of their market forecast and analysis of the global consumption of Fiber Optic Sensors.
According to the study, the combined use of Distributed and Point (local) fiber optics sensors reached $3.38 Billion last year (2016), and the worldwide value is forecast to reach $5.98 Billion in 10-years (2026). Market forecast data in this study report refers to consumption (use) for a particular calendar year; therefore, this data is not cumulative data.
Both the American region and the EMEA region held similar market share in the overall (distributed- and point-types) fiber optic sensor value last year. The Europe, Middle East, Africa region (EMEA) held a very slight lead in relative market (value) share last year; however, the Asia Pacific region (APAC) is projected to take-over the leadership position during the forecast period.
The EMEA region is forecast to have a strong role in the use of distributed fiber optic systems, driven by the region’s use of systems in aviation, as well as in the
Petrochemical, Natural Resources, Energy/Utility application categories.
In terms of fiber optic point sensors, the American region is forecast to maintain the market share lead throughout the 1st-half of the forecast period (2016-2021), mostly led by the use of Fiber Optic Gyros (FOGs) in the Military/Aerospace application category. The consumption values are based on the end-user application and the end-user region.
FOGs held a 65 percent market share of the worldwide Point fiber optic sensor consumption value in 2016. “All regions, thanks mainly to increases in the use in aviation and military critical mission applications (Unmanned Aerial Vehicle/UAV and missile guidance, navigation, north finding/tracking, robotics, aviation and aeronautics and other) are forecast to show impressive increase consumption quantity (volumes) and values for the FOG systems,” said Stephen Montgomery, Director of the Fiber Optics Components group at ElectroniCast Consultants.
The market forecast of the Distributed Sensors is segmented by the following applications:

• Manufacturing Process/Factory
• Civil Engineering/Construction (buildings, bridges, tunnels, etc)
• Military/Aerospace/Security
• Petrochemical/Energy/Utilities/Natural Resources
• Biomedical/Science

The Fiber Optic Point Sensor Forecast further segmented by the following sensing/measuring quantity (measurand) types:

• Mechanical Strain
• Temperature
• Pressure
• Chemical, Gas, Liquid
• Vibration, Acoustic, Seismic
• Displacement, Acceleration, Proximity
• Electric, Current and Magnetic Field - Fiber Optic Sensors
• Rotation (such as Fiber Optic Gyroscopes: FOGs)

“ElectroniCast counts each Point fiber optic sensor as one unit; however, the volume/quantity (number of units) of Distributed fiber optic sensors is based on a complete optical fiber line/link, which we classify as a system. Since a distributed optical fiber line (system) may have 100s of sensing elements in a continuous-line, it is important to note that we count all of those sensing elements in a distributed system as one (system) unit – only. Distributed fiber optic sensor systems involve the optic fiber with the sensors embedded with the fiber; also included is the optoelectronic transmitter/receiver, connectors, optical fiber, cable (fiber jacket) the sensor elements, and other related components,” Montgomery added.
According to ElectroniCast, the combined use of Distributed and Point fiber optics sensors reached $3.38 Billion in 2016…

Two Types Of Polarization Beam Combiners & Splitters

Polarizing Beam combiners / splitters are the devices used to combine two polarized light signals or split single non-polarized light into two polarized parts. These combiners and splitters are designed and developed to split light beams by deploying the polarization state and not by wavelength or intensity.

The polarizing beam splitters / combiners typically have 0° or 45° angle of incidence and a 90° division between the beams; this generally depends on the configuration. There are two types of Polarization beam combiners and splitters; these are described below:

1. Incoherent Polarization Combining / Splitting

The Incoherent combining or splitting is the simpler variant and the basic technique. In this method, the resulted beams of two broad area laser diodes are sent onto a thin-film polarizer so as to reflect one of the beams while transmit the other; both of these beams then propagate in the same direction. As a result, one attains an unpolarized beam (with the combined optical power of the input beams) and the same beam quality. Consequently, the brightness gets nearly doubled.

This technique is often used for any-a-applications, for instance, end-pumping of a solid state laser with an increased power. However, the technique is not suitable for power scaling.

2. Coherent Polarization Combining / Splitting

With coherent beam combining or splitting it is viable to attain a linear polarized state in the output, if two mutually coherent beams are combined. If two ports have the equal input powers, the output polarization would be typically rotated by 45° -depending on the polarization direction of any of the input beams.

Also, the coherent polarization combining can be repeated several times because of the linear output polarization. Thereby, this technique is suitable for power scaling.

A polarization beam combiner and splitter is often used in photonics instrumentation, optics and semiconductors to transmit p-polarized light while reflecting s-polarized light. These hold a world of worth when it comes to optics, telecommunication and fiber applications, and make the working effective as well as effortless.
