Abstract

L'invention concerne un instrument optique binoculaire à mise au point automatique. L'instrument comporte deux objectifs qui sont également utilisés pour la mesure optique de distance, et des miroirs fixe et mobile dans les trajets optiques derrière les oculaires. Les images produites par ces miroirs sont amenés en coïncidence en déplaçant le miroir mobile qui produit un signal reçu par un moteur pas à pas qui commande la mise au point. L'invention s'applique notamment à des jumelles, etc.
