Abstract

L'invention concerne un dispositif de télémétrie apte à être aéroporté, comprenant un laser configuré pour émettre au moins une impulsion de lumière. Selon l'invention, un tel dispositif de télédétection comprend : - des moyens de division de ladite impulsion émise en une pluralité d'impulsions secondaires ; - des moyens de détection de la fraction réfléchie de chacune desdits impulsions secondaires ; - des moyens de mesure, pour chacune desdites impulsions secondaires, d'une donnée représentative de la durée du trajet de la lumière entre l'émission de ladite impulsion émise par ledit laser et la réception de ladite fraction réfléchie de ladite impulsion secondaire par lesdits moyens de détection ; - des moyens de détermination, pour chacune desdites impulsions secondaires, d'une information représentative de la distance entre ledit dispositif et la position de réflexion de ladite impulsion secondaire sur la surface du sol, à partir de ladite donnée représentative de la durée du trajet de la lumière associée à ladite impulsion secondaire.
