Abstract
La présente invention a trait à un dispositif de mesure de charge et de déflection structurelle, pour fixation sur un axe. Le dispositif comprend au moins un dispositif émetteur de faisceau lumineux relié à l'axe et capable d'émettre au moins un faisceau lumineux et au moins un dispositif de captage de position lumineuse relié à l'axe. Le dispositif de captage est situé relativement au dispositif émetteur du faisceau lumineux pour recevoir au moins un faisceau lumineux du dispositif émetteur du faisceau lumineux; il peut être actionné pour calculer la position du faisceau lumineux reçu sur sa surface.
