Abstract

Dispositif directeur de faisceau optique comportant un moyen réflecteur qui permet de diriger le faisceau le long d'une trajectoire choisie à l'avance traversant un échantillon. Dans cet appareil, un élément de renvoi de faisceau tel qu'un drièdre trirectangle 37 est associé à chaque trajectoire d'échantillonnage 23d. Le moyen réflecteur 29, 39 est monté de manière à pouvoir tourner autour de l'axe d'un arbre 31. Un moyen de détection et un codeur de position angulaire d'arbre déterminent l'orientation angulaire du moyen réflecteur 29, 39. Un moyen de commande sensible à des signaux du moyen de détection ajuste l'orientation angulaire du moyen réflecteur. Application aux spectrographes.
