Title (EN) OPTICAL DEVICE FOR MEASURING DISPLACEMENT VELOCITY OF A FIRST MOVABLE ELEMENT WITH RESPECT TO A SECOND ELEMENT
(FR) DISPOSITIF OPTIQUE DE MESURE DE LA VITESSE DE DEPLACEMENT D’UN PREMIER ELEMENT MOBILE PAR RAPPORT A UN SECOND ELEMENT
Abstract: front page image
(EN)The invention relates to an optical device (1) for measuring the displacement velocity of a first movable element in relation to a second element which is fixed to one of said elements and comprises two lasers (2a, 2b) transmitting two incident beams (3a, 3b) towards the other element. The inventive device (1) comprises photosensitive linear arrays for front (9) and rear (10) detection which are substentially perpendicular to each other. Additional front (12) and rear (13) photosensitive linear arrays are disposed at a distance from the photosensitive front (9) and rear (10) linear arrays. A processing circuit (11) is connected to the photosensitive linear arrays (9, 10, 12, 13) and determines the longitudinal and/or transversal displacement velocity of the movable element. Said circuit also determines the distance between the device (1) and the other element by means of optical triangulation and corrects the longitudinal and/or transversal displacement velocity value according of said distance.
(FR)Le dispositif optique de mesure (1) de la vitesse de déplacement d'un premier élément mobile par rapport à un second élément est fixé à l'un des deux éléments et comporte deux lasers (2a, 2b) émettant deux faisceaux lumineux incidents (3a, 3b) en direction de l'autre élément. Le dispositif (1) comporte des barrettes photosensibles de détection avant (9) et arrière (10), disposées sensiblement perpendiculairement l'une par rapport à l'autre. Des barrettes photosensibles supplémentaires avant (12) et arrière (13) sont disposées à l'écart des barrettes photosensibles avant (9) et arrière (10). Un circuit de traitement (11), connecté aux barrettes photosensibles (9, 10, 12, 13), déterminent la vitesse de déplacement longitudinale et/ou transversale de l'élément mobile. Il détermine, par triangulation optique, la distance entre le dispositif (1) et l'autre élément et corrige la valeur de la vitesse de déplacement longitudinale et/ou transversale en fonction de cette distance.
