Abstract

L'APPAREIL A IMAGE THERMIQUE CONTIENT UN POLYGONE DE BALAYAGE PERMEABLE AUX RAYONS INFRAROUGES DISPOSE DERRIERE UN SYSTEME D'OBJECTIF ET POUVANT TOURNER AUTOUR DE DEUX AXES PERPENDICULAIRES ENTRE EUX, NOTAMMENT AUTOUR DE L'AXE OPTIQUE ET AUTOUR DE L'AXE DE ROTATION DU POLYGONE DE BALAYAGE, AXE QUI EST PERPENDICULAIRE AU PREMIER AXE. LE RAYON SORTANT DU POLYGONE TRAVERSE EN OUTRE UNE OPTIQUE D'INVERSION TOURNANT EGALEMENT AUTOUR DE L'AXE OPTIQUE MAIS A LA MOITIE DE LA FREQUENCE ANGULAIRE DU POLYGONE DE BALAYAGE. DE PLUS, ON A PREVU UN DISPOSITIF DETECTEUR DE RAYONS INFRA-ROUGES A PLUSIEURS CANAUX AUQUEL EST CONNECTE UN AMPLIFICATEUR-SOMMATEUR A PLUSIEURS CANAUX QUI EST SYNCHRONISE A LA FREQUENCE DE ROTATION DU POLYGONE DE BALAYAGE AUTOUR DE SON PROPRE AXE. CETTE ROTATION DU POLYGONE DE BALAYAGE FOURNIT AUSSI SIMULTANEMENT LA FREQUENCE DE DEVIATION RADIALE POUR LA REPRESENTATION DE L'IMAGE. APPLICATION: VISIERE AVEC SYSTEME A IMAGE THERMIQUE.
