Abstract
Télémètre optique comprenant un laser impulsionnel dont le rayonnement est réfléchi par une cible, un oscillateur local à émission continue de fréquence voisine de celle du laser, un mélangeur recevant le rayonnement réfléchi et celui de l'oscillateur local et un photodétecteur délivrant un signal dit de battement réflexion qui est appliqué à un chronometre pour la détermination de la distance de la cible. Il est prévu selon l'invention un séparateur pour prélever une partie de l'énergie émise par le laser impulsionnel et la diriger vers le mélangeur, des moyens reliés audit détecteur pour mémoriser avant le retour du rayonnement réfléchi le signal de battement émission ainsi obtenu et des moyens pour faire battre le signal de battement émission et le signal de battement réflexion, le signal résultant étant appliqué au chronomètre.
