Fiber Bragg Grating Sensors: A Market overview

Alexis Mendez

MCH Engineering LLC Alameda, CA (USA)

Over the last few years, optical fiber sensors have seen increased acceptance and widespread use for a variety of applications ranging from structural sensing and health monitoring of composites and structures in civil and aeronautic areas; to downhole pressure and temperature sensors for oil and gas reservoir monitoring; to high voltage and high current sensing systems for the power industry—to name just a few.

Optical fiber sensor operation and instrumentation have become well understood and developed. And a variety of commercial discrete sensors based on Fabry-Perot (FP) cavities and fiber Bragg gratings (FBGs), as well as distributed sensors based on Raman and Brillouin scattering methods, are readily available along with pertinent interrogation instruments.   Among all of these, FBG based sensors, more than any other particular sensor type, have become widely known and popular within and out the photonics community and seen a rise in their utilization and commercial growth.

Given the intrinsic capability of FBGS to measure a multitude of parameters such as strain, temperature, pressure, chemical and biological agents—and many others—coupled with their flexibility of design to be used as single point or multi-point sensing arrays and their relative low cost, make them ideal devices to be adopted for a multitude of different sensing applications and implemented in different fields and industries.  However, some technical hurdles and market barriers need to be overcome in order for this technology—and fiber sensors in general—to gain more commercial momentum and achieve faster market growth.

An overview of the commercial status of FBG-based sensors and market trends will be given along with an analysis of the estimated market size, segments, players, driving factors and most relevant commercial applications.
