Abstract:
(EN) The various embodiments described here comprise an OFDR system and technique that may be used for inference of strain or temperature over a large dynamic range using a narrow wavelength range. Embodiments of the sensor fiber may be composed of one or more multi-spectral-feature sensors, each sensor exhibiting several spectral features that together offer coverage over a wavelength range corresponding to the desired system strain and or temperature dynamic range.
(FR) Les divers modes de réalisation de l'invention concernent un système et une technique OFDR pouvant être utilisés pour l'inférence d'une contrainte ou d'une température sur une large plage dynamique à l'aide d'une plage de longueurs d'onde étroite. Des modes de réalisation de la fibre de capteur peuvent être composés d'un ou plusieurs capteurs à caractéristiques spectrales multiples, chaque capteur présentant plusieurs caractéristiques spectrales offrant ensemble une couverture sur une plage de longueurs d'onde correspondant à la contrainte de système souhaitée et/ou à la plage dynamique de température.
