Abstract

L'invention concerne un dispositif électro-optique (18) comprenant une source de lumière laser (20), qui émet au moins un faisceau d'impulsions lumineuses, un dispositif d'orientation de faisceau (24), qui transmet et balaye ledit faisceau sur une scène cible (22), et une matrice (28) d'éléments de détection (44). Chaque élément de détection délivre un signal indiquant un temps d'incidence d'un photon unique sur l'élément de détection. De l'optique de collecte de lumière (27) met en image la scène cible balayée par le faisceau transmis sur la matrice. Des circuits (50) sont couplés pour n'actionner les éléments de détection que dans une région sélectionnée (70) de la matrice et pour balayer la région sélectionnée sur la matrice en synchronisation avec le balayage dudit faisceau.
