摘要

FBG sensor with an optical fiber (4) having an FBG (4a), in which - the optical fiber (4) is immobilized between two fixing elements (5a, 5b) whose lower sides are configured as adhesive surfaces, in the that the optical fiber (4) and the fasteners (5a, 5b) - are embedded in a protective mass (6) based on a soft silicone rubber or a plastic with comparable mechanical properties and - the fiber (4) it is embedded between a thin upper sliding sheet and a thin lower sliding sheet (7, 8) based on Teflon or a plastic with a small coefficient of friction comparable to that of Teflon, and in which - the lower side of the sheet Lower sliding (7) is located in a plane with the adhesive surfaces of the fasteners (5a, 5b).
