Abstract

Dispositif permettant de stabiliser le flux lumineux moyen reçu par un détecteur photoélectrique à très haute sensibilité. Il comporte un diaphragme 6 à pales articulées, un dispositif d'entraînement en rotation 11, 12, 13 du diaphragme autour de l'axe optique Z de l'objectif optique 1 de focalisation, pour déplacer les pales en fonction de la force centrifuge créee, et des circuits de traitement produisant successivement la mesure 7 de la valeur moyenne SVm du signal détecté, la comparaison différentielle 8 à une valeur de réference VR et l'asservissement 9, 10, Il de la vitesse de rotation en fonction du résultat epsilon de comparaison. L'invention s'applique avantageusement à des systèmes autodirecteurs télévision à senseur CCD.
