Abstract (en)

[origin: WO2019243745A1] The invention concerns the field of integrated health monitoring using Bragg grating optical fibre sensors. It concerns such a sensor and methods for locating and installing this sensor on a support. According to the invention, the Bragg grating optical fibre sensor (30) comprises an optical fibre (31) in which at least one set of patterns (33) forming a Bragg grating is written, the optical fibre further comprising a set of microstructures (32) in the vicinity of each Bragg grating, the microstructures being separate from the patterns forming the Bragg grating, each microstructure (32) being capable of scattering a portion of a light beam within a predetermined range of scattering wavelengths.
