What is FBG array

"FBG array" refers to a Fiber Bragg Grating (FBG) array. FBG is a fiber optic sensor technology that utilizes the grating structure within the optical fiber to measure physical quantities such as strain, temperature, displacement, force, vibration, and more.

An FBG array represents a configuration where multiple FBG measurement points are distributed or arranged on one or multiple optical fibers. This can form a single-fiber OFSCN (Optical Frequency Scanning) FBG sensor with multiple measurement points or a multi-fiber OFSCN FBG sensor with multiple measurement points on each fiber.

By deploying the aforementioned OFSCN FBG sensors at various positions, an FBG array allows simultaneous monitoring of multiple measurement points, providing comprehensive three-dimensional environmental information on the OFSCN FBG demodulator software platform.

The applications of FBG arrays are diverse, especially in the field of structural monitoring. For instance, deploying an FBG array on bridges or buildings enables real-time monitoring of structural deformations, strains, and vibrations. Additionally, FBG arrays find utility in areas such as oil and gas pipelines, wind turbine blades, etc., enabling high-precision measurements at multiple points in complex environments.

In summary, an FBG array, incorporating multiple FBG sensors distributed at different positions, offers a flexible and high-precision fiber optic sensing solution suitable for various application scenarios.

The concept of an FBG array integrates Fiber Bragg Grating, FBG sensors, and the OFSCN FBG demodulator software platform.
