Title (EN) DEVICE FOR THE OPTICAL DETECTION AND MEASUREMENT OF LINEAR MOVEMENTS
(FR) DISPOSITIF DESTINE A LA DETECTION ET LA MESURE OPTIQUES DE MOUVEMENTS LINEAIRES
Abstract: front page image
(EN)A description is given of a device (1) for the optical detection and measurement of the linear movements of a body (2) in the direction of its axis (Z-Z), comprising a surface (3), integral with the body (2) which makes the said movements, carrying a scale (8) formed by a plurality of equidistant parallel ribs (4n) arranged perpendicularly to the direction of the movements to be detected, and a fixed reading head (7) capable of detecting the number of ribs (4n) which pass through its reading field in both directions, characterized in that the said surface (3) is the external surface of a solid of revolution (5) coaxial and integral with the said body (2), the said ribs (4n) forming circumferences lying on parallel planes perpendicular to the axis of the aforesaid solid of revolution (5).
(FR)L'invention concerne un dispositif (1) destiné à la détection et la mesure optiques de mouvements linéaires d'un corps (2) le long de son axe (Z-Z). Le dispositif comprend une surface (3) faite intégrale avec le corps (2) faisant les mouvements en question et qui est munie d'une règle (8) formée par plusieurs ailettes parallèles équidistantes (4n) aménagées perpendiculaires à la direction des mouvements à détecter, ainsi que d'une tête de lecture fixe (7) capable de détecter le nombre d'ailettes (4n) qui passent à travers son champ de lecture dans les deux directions. Le dispositif est caractérisé en ce que la surface (3) constitue la surface externe d'un solide de révolution (5) coaxial et qu'elle est faite intégrale avec le corps (2). Les ailettes (4n) forment des circonférences qui s'étendent dans des plans parallèles, perpendiculairement à l'axe dudit solide de révolution (5).
