Applications of Fiber Bragg Grating Sensors in the Industry

Abstract

Industrial Revolutions marked periods of exponential growth in the industrial sector. Among the technologies immersed in this area is fiber optics, which was initially used in the telecommunications industry, but is currently present in several industrial sectors. More specifically, this work addresses its applications in Instrumentation associated with the concept of Bragg grids. In this paper is published a brief introduction to fiber Bragg gratings (FBG), aiming to present an analysis of the most recent articles related to the use of fiber Bragg grating in industrial sensors. We selected 19 papers to show the results and the positive and negative data of this technology. Although it is a promising technology, it still needs standardization with the conventional industry environment.

Numerical Investigation of Stress-Strain State Effects on Strain Measurements with Fiber Bragg Grating Sensors

“…Currently, fiber-optic sensors (FOSs) based on fiber Bragg gratings (FBG) are in high demand for monitoring the mechanical state of structures [1][2][3]. These sensors, due to their compact size, the ability to be embedded into the structure, resistance to electromagnetic interference and high sensitivity, have found widespread applications in such areas as civil engineering [4,5], aerospace [6,7] and geotechnical [8] industries.…”

Accuracy of scanning interrogation of FBG sensors

“…Fibre Bragg gratings (FBGs) were found to be specific wavelength selective fibre elements with great prospects in optical signal filtering. They were soon investigated with objective to use their facilities in sensing, first for scientific, then for commercial applications [9][10][11][12][13][14][15][16].…”
