Abstract

L'invention est relative à un procédé et à un dispositif d'analyse d'une cible pyroélectrique pour tube de prise de vues. Le procédé selon l'invention consiste à effectuer une mémorisation du signal inscrit sur la cible au cours d'une irradiation par une neutralisation des charges électriques apparaissant au niveau de la cible lors de l'irradiation, la mémorisation précédant l'étape de lecture proprement dite de la cible effectuée après refroidissement de celle-ci. Le dispositif selon l'invention comporte dans une enveloppe à vide 1 une cible pyroélectrique 2 dont la face 22 est orientée vers des moyens générateurs d'au moins un faisceau électronique 5. Les moyens générateurs 5 sont connectés à des moyens de commande 6 d'intensité d'émission du faisceau, et la cible pyroélectrique 2 est connectée à des moyens de commande en tension 7. Les moyens de commande 6 et 7 sont commandés par un circuit de commande commun 8. Application aux tubes de prise de vues en rayonnement infrarouge.
