Abstract

Dispositif d'écartométrie comprenant un objectif de focalisation, un dispositif de balayage suivant une direction, un dispositif de détection et un circuit pour délivrer, à partir des signaux de sortie du dispositif de détection, deux signaux caractéristiques des coordonnées X et Y de la source, le dispositif de détection comprenant deux détecteurs filiformes disposés en V. Il est prévu un circuit de filtrage, associé à chaque détecteur, pour invalider le signal émis par le détecteur considéré lorsque l'instant d'émission se situe en dehors d'une fenêtre temporelle définie pour chaque période de balayage, la fenêtre relative à la (n + 1)**me période étant centrée sur l'instant tn + (tn - t n-1 ) et ayant une largeur k | tn - tn-1 | k étant un nombre positif.
