Fiber Bragg gratings stand out among other fiber optic sensors as the most developed and prominent technology for measurement of strain, vibrations, temperature, and pressure. FBG sensors have attracted significant interest in structural health monitoring due to numerous advantageous properties:
- immunity to electromagnetic interference;
- intrinsic fire safety;
- low invasiveness;
- minimum aesthetic impact;
- possibility to send the data remotely using the same sensing fiber.
There are multiple sensing advantages that FBG sensors provide. First of all, FBG sensors perform with an excellent balance between complexity and performance, which is one of the most attractive qualities of fiber Bragg grating sensors for structural health monitoring. Secondly, FBG sensors are able to work in low signal-to-noise ratios better that other optic sensors. Moreover, fiber Bragg grating sensors are predictable and less dependent on the temperature of the surrounding environment, as well as are well-suited for multiplexed optical sensor networks.
Over the past decade, structural health monitoring has attracted a lot of attention as modern technology develops and new materials and compounds are used in the construction of buildings and structures. Structural health monitoring involves collection and analysis of information obtained through measurements of the structure. The results of data analysis are used to assess damage and evaluate the performance of the structure under harsh conditions.
FBG sensor structural health monitoring has become an important tool for assessing the performance of different structure and measurements of temperature, strain, pressure, displacement, etc.
Fiber optic strain gauge is welded directly to the surface of the metal structure (pipes, beams, etc.), and it has a protective silicone cover. Fiber optic strain sensors are durable and stable, widely used for civil engineering constructions, particularly they reinforce concrete structures exceptionally well.
Fiber Bragg Grating strain sensors demonstrate lots of advantages compared to the regular electrical strain gauges. Namely, they are immune to electromagnetic interference and power shortages. Compact size devices provide the most accurate measurements. FBGs are, literally, the best strain sensors right now.
