Abstract

L'invention concerne un capteur de choc comportant:<br/>un réseau de fibres optiques (12) destinées à être disposées sur une partie du corps humain et arrangées pour constituer une matrice à lignes et colonnes, et<br/>des moyens électroniques (14) connectés audit réseau et exerçant les fonctions de:<br/>- injection à une extrémité de chaque fibre d'un faisceau lumineux;<br/>- mesure de l'intensité du faisceau délivré à l'autre extrémité de chaque fibre;<br/>- comparaison, pour chaque fibre, de l'intensité du faisceau injecté avec l'intensité du faisceau délivré; et<br/>- en cas de diminution de l'intensité de la lumière délivrée par rapport à celle injectée, fourniture et affichage d'une information identifiant la fibre de la ligne (16, 18) et la fibre de la colonne (20) qui ont fourni un faisceau affaibli suite à un choc, cette information permettant de localiser le point de l'impact au croisement des fibres concernées.The invention relates to a shock sensor comprising: a network of optical fibers (12) intended to be arranged on a part of the human body and arranged to form a matrix with rows and columns, and means electronic means (14) connected to said network and carrying out the functions of: - injecting at one end of each fiber a light beam; - measuring the intensity of the beam delivered at the other end of the beam; each fiber; comparing, for each fiber, the intensity of the injected beam with the intensity of the beam delivered; and in the case of a decrease in the intensity of the light delivered relative to that injected, providing and displaying information identifying the fiber of the line (16, 18) and the fiber of the column (20). ) which provided a weakened beam following a shock, this information making it possible to locate the point of impact at the crossing of the fibers concerned.
