Abstract

L'invention concerne un dispositif donnant une mesure de la distance entre lui et un objet et mettant en mouvement un élément jusqu'à une position représentative de la distance mesurée. Le dispositif comprend des moyens de balayage comportant des moyens optiques pouvant se mouvoir à travers une rangée de positions dont l'une est représentative de ladite distance, des moyens pour faire mouvoir les moyens optiques à travers une rangée entière ou de balayage pour chaque distance à mesurer, des moyens pour fournir un signal indicatif de ladite position particuière, et des moyens de commande répondant audit signal en faisant mouvoir l'élément jusqu'à ladite position représentative. Application courante.
