Abstract
Procédé et dispositif pour la détection d'un objet apte à rétroréfléchir la lumière.Selon l'invention, en synchronisme avec chaque impulsion laser d'éclairement, on forme deux images simultanées à des longueurs d'onde (lambda1, lambda2) différentes, l'une d'elles correspondant à la longueur d'onde (lambda1) desdites impulsions laser, et on forme la différence entre lesdites deux images.
