Abstract

Télémètre à laser utilisant le principe de la mesure du temps de parcours d'une impulsion de lumière au moyen de deux canaux ou voies, l'une de ces voies - appelée voie de référence - servant à obtenir le signal de départ, et l'autre voie - appelée voie de mesure - à obtenir le signal d'arrêt, caractérise en ce que l'on monte, en tant que résistance de travail ou de charge, dans le circuit récepteur à diodes, un circuit de résonance parallèle, qui comporte une bobine et la capacité à couche d'arrêt ou de blocage de la diode réceptrice, ainsi qu'une capacité externe supplémentaire montée en parallèle.
