Fiber Bragg Grating Applications

Geodynamics

FBG sensors can be mounted to the surface，or embedded in of the geological structure, by measuring the strain distribution of the geological structure, the local load and health status of the geological structure can be predicted.

Spacecraft and Ship

In order to realize the structural health monitoring of large aircraft, multiple fiber grating sensors can be installed at different measurement points, and combined with advanced communication technology, a distributed intelligent sensor network with super functions can be formed. Real-time monitoring ensures timely alarms before accidents occur, while reducing maintenance costs, inspection time and downtime.

Civil Engineering Structure

Since the fiber grating sensor was first embedded in concrete beam, it has been widely used in mechanical parameter measurement and structure health monitoring of bridges, dams, pipelines, tunnels, buildings and roads. Among them, one of the fields with the most applications of fiber grating sensors is the structure health monitoring of bridge.

Petrochemical Industry

FBG sensor has the characteristics of high temperature resistance, high pressure resistance, strong corrosion resistance, and electromagnetic interference resistance, which makes it possible to use oil logging technology to measure physical quantities such as downhole temperature, flow rate and pressure, so as to make predictions to solve various problems that may arise in advance.

Power Industry

Fiber grating sensors are ideal for power industry applications due to their immunity to electromagnetic fields and low-loss transmission over long distances. The load capacity of the wire, the temperature of the transformer winding, and the high current can all be measured by the fiber grating sensor.

Medical and Biotech

Due to the high flexibility, high sensitivity, good biocompatibility and other characteristics of polymer FBG, they play an irreplaceable role in biomedical sensing and detection, and have received extensive attention in the academic and medical circles in recent years.

Telecommunication

Fiber bragg grating has the characteristics of small additional loss, small size, good coupling with optical fiber, and integration with other optical fiber devices, making it a key device in all-optical networks.

Chemical Sensing

In scientific research, analytical chemistry, environmental protection and industrial production, pH is an important physical parameter, which should be accurately measured. Compared with traditional measurement methods, optical sensors have numerous advantages, such as suitable for remote sensing, miniature size, chemical and biological inert.
