Abstract

L'invention est relative à un détecteur d'amplitude de vibration. Un élément ou lame est relié à une palette s'étendant entre des guides de lumière à fibres optiques opposés. La palette porte une partie de masque avec des fentes espacées uniformément dans le sens du déplacement de la palette et interposées dans le parcours de la lumière entre les guides. L'un des guides possède un masque stationnaire avec au moins une fente correspondant en dimension et orientation à celles de la palette. Lors d'une vibration de l'organe, la lumière est alternativement transmise et coupée et les minima de transmission sont comptés pour déterminer l'amplitude de vibration. Utilisation dans le domaine de la mesure à distance des vibrations.
