Abstract
There is provided a method for manufacturing an optical-fibre sensor device, including an enclosure defining a cavity and an optical-fibre sensor including an optical-fibre and a device for holding the sensor rigidly connected to the optical fibre, the optical fibre passing through the holding device between two attachment points. The method comprises: positioning the optical-fibre sensor in the enclosure to pass the fibre through two passage openings provided on the enclosure, which defines two optical-fibre portions in the enclosure, on either side of the holding device, each fibre portion extending between one of the attachment points and one of the passage openings; holding the optical-fibre sensor in position; performing a differential elongation of the enclosure relative to the optical-fibre sensor in the longitudinal direction and towards the outside of the enclosure, the optical-fibre sensor remaining held in position; attaching the optical fibre to the enclosure at the passage openings.
