Abstract (en)
[origin: WO2013023976A1] The invention relates to a deformation measurement sensor operating in a hostile environment and including an integrated optical movement measurement module, and to a measurement system using said sensor. The sensor (2) includes: an enclosure (12) comprising an opening (14); a movable element (16) having a first surface (22) that is brought into contact with an object (4) that can deform, for example a nuclear fuel rod, and a second surface (24) that is reflective and extends into the enclosure through the above-mentioned opening; a sealed, resilient connecting component (18) performing a return function between the element and the enclosure; and, inside the enclosure, a module (20) for creating an interference light (36) using a light (30) reflected by the second surface of the element. According to the invention, deformation of the object results in a modification to the interference light that is representative of the deformation.
