Abstract

L'invention concerne un détecteur de rayonnement invisible. Il comporte un cristal scintillateur avec une surface formant fenêtre, couplée optiquement avec un photodétecteur, de préférence à semi-conducteur, et dont les autres surfaces diffusent la lumière. La surface formant fenêtre voit toutes les autres surfaces et laisse passer les photons lumineux de cristal vers le photodétecteur. L'invention s'applique notamment à des dispositifs de tomographie par calculateur.
