Fiber sensing elements based on Bragg gratings (FBG) are a prospective basis of sensors for detecting deformations in measuring systems, in particular, for integrated control of various structures. The possibility of their application in the structure of polymer composite material for aerospace. These constraints have led researchers and engineers to explore optical fiber sensing technologies, with Fiber Bragg Grating (FBG) sensors emerging at the forefront due to their high sensitivity, immunity to electromagnetic interference, and capability for distributed measurements across critical. In steel structure engineering, deformation monitoring is one of the key factors to ensure safe construction and stable operation. Traditional deformation monitoring methods usually use contact measurement, which has problems such as high operating costs, limited monitoring range, high monitoring. To address the issues of decreased accuracy and poor stability in distributed transfer alignment caused by factors such as wing deflection and deformation in complex flight environments, this paper proposes a wing-distributed transfer alignment method based on Fiber Bragg Grating (FBG). This paper. er Bragg Grating (FBG) fiber-optic sensors for embedded, high-precision deformation monitoring in civil infrastructure.
