Abstract
Dispositif photoélectrique incrémental de mesure des longueurs et des angles avec trajet parallèle des rayons d'éclairement pour la détermination de la position relative de deux objets sans moyens optiques formant l'image entre une échelle et une plaque de balayage comportant respectivement une grille réticulée à constante de grille déterminée et déplaçables l'une par rapport à l'autre à une distance mutuelle parallèle donnée. La constante de grille PM de l'échelle 5 et la constante de grille PA de la plaque de balayage 8 diffèrent entre elles d'un multiple n.
