Abstract

La présente invention est relative à des perfectionnements à un instrument de télémétrie laser. L'instrument de télémétrie conforme à l'invention comporte un ensemble d'émission laser émettant des impulsions laser vers une cible qui renvoie des impulsions diffusées se propageant avec la lumière visible, au travers d'un objectif, vers un séparateur sélectif qui dirige d'une part lesdites impulsions diffusées vers un capteur de réception photosensible et d'autre part ladite lumière visible vers un élément de visée et il est caractérisé par le fait qu'il comporte, après l'objectif, un réflecteur principal réfléchissant les impulsions laser diffusées et la lumière visible vers ledit séparateur sélectif qui est placé à proximité dudit objectif.
