Abstract:
An optical fibre pressure sensor comprising a central core which takes a form of a support (44) of substantially cylindrical shape, at a surface of which two diametrically opposite grooves (46) are made, which extend parallel to the longitudinal axis of said support (44) and in which an optical fibre (10) is housed without stress, said support (44) and said optical fibre (10) being inserted in a covering (48) which is slit longitudinally and in which a plurality of clamping jaws (50) have been cut, said jaws (50) being used to bend the optical fibre (10) by elastic pressure and to modify locally its radius of curvature, an assembly thereby formed being finally covered in a sheath (52).
