Abstract

a. L'invention concerne un dispositif de balayage linéaire stéréoscopique. b. L'axe de rotation du prisme de renvoi 1 est parallèle à la direction du déplacement ou du vol du support d'instrument ou fait un angle aigu avec cette dernière; le dispositif à miroirs comporte un miroir de renvoi 6 disposé au-dessus du prisme de renvoi 1; l'agencement est tel qu'un rayon primaire de balayage est dévié directement et seulement par l'intermédiaire du prisme de renvoi 1 vers le dispositif de détection 7, alors qu'un rayon secondaire de balayage est dévié vers ledit dispositif de détection 7 par l'intermédiaire du miroir de renvoi et ensuite seulement par l'intermédiaire du prisme de renvoi 1 et d'un dispositif optique convergent. c. Application aux dispositifs de balayage linéaires stéréoscopiques pour fournir des lignes de balayage convergentes et rectilignes d'objets éloignés.
