Abstract

Système de structure physique relativement compacte. Il comprend un élément de détection du rayonnement à l'état solide 10 pour faire varier la valeur d'un paramètre électrique sensible à la grandeur du flux incident total de photons optiques et du rayonnement externe, un premier dispositif 20 pour créer un flux de photons optiques qui vient frapper cet élément de détection, un second dispositif 21, R1 pour entraîner une variation du flux du premier dispositif en réponse à une variation du paramètre électrique pour que l'on puisse maintenir pratiquement constante la valeur de ce paramètre électrique, et, un troisième dispositif 28 pour contrôler le flux optique du premier dispositif pour obtenir un signal de sortie du système ayant une amplitude proportionnelle au flux de rayonnement produit extérieurement. Application à la tomographie par rayons X couplée avec un ordinateur.
