Abstract
The invention concerns a device for locally measuring strains within a measurement volume that comprises a test body formed from a homogeneous material of known mechanical properties and ellipsoidal in shape intended to be included in the measurement volume, at least one measurement optical fiber for measuring deformation embedded within said test body and means for linking the at least one measurement optical fiber to a system designed to stimulate the at least one measurement optical fiber, detect signals coming from the fibers and, by means of an electronic system capable of carrying out calculations, determine strains from at least one of the detected signals and known mechanical properties.
