Abstract
Un dispositif de vision nocturne et un télémètre (10) à laser intégrés permettent d'obtenir des images d'une scène de nuit comme de jour au moyen d'un tube (14) intensificateur d'image, et ils permettent d'effectuer des opérations de télémétrie à laser de jour comme de nuit. Dans le mode de fonctionnement de télémètre à laser, le dispositif (10) projette une impulsion de lumière laser sur une scène observée et un circuit (62) d'alimentation et de télémètre à laser du dispositif (10) utilise temporairement le tube (14) intensificateur d'image comme capteur pour détecter la lumière laser réfléchie. Pendant la télémétrie au laser, la production d'image est arrêtée pendant un intervalle de temps très court et un circuit de préamplification (66b) associé au tube (14) intensificateur d'image permet d'obtenir un signal de sortie électrique en réponse à la réception de lumière laser réfléchie par un objet de la scène observée.
