Abstract

Dispositif de balayage optique notamment pour l'infra-rouge. L'accouplement entre les éléments de balayage d'azimut et d'élévation est un miroir concave incliné par rapport à l'axe du faisceau en vue de diriger le rayonnement lumineux sur un miroir plan oscillant constituant un élément de balayage d'élévation et placé pratiquement à la même longueur de chemin optique du miroir concave que l'élément de balayage d'azimut, le miroir de balayage d'élévation étant monté de façon à osciller autour d'un axe qui est incliné par rapport au plan du miroir de façon à compenser la rotation de l'image. Application aux analyseurs à infra-rouge.
