Abstract

L'invention a pour objet un dispositif destiné à stabiliser la ligne de visée d'une caméra de télévision, montée sur un véhicule. La caméra 1 est montée, par des éléments élastiques 2, sur une surface 3 du véhicule. La caméra 1 porte un miroir plan 4 éclairé par une diode émettrice 5 avec un faisceau parallèle formé par une lentille autocollimatrice 6. La lumière de la diode 5 est réfléchie par le miroir 4, ceci à travers la lentille 6 et est focalisée sur un détecteur 7. Le mouvement du véhicule fait tourner la caméra autour des éléments 2, relativement au plan de référence 3. Ce mouvement est décomposé en deux composantes orthogonales 9 entraînant une erreur angulaire de la ligne de visée 8 qui vient occuper une nouvelle position 10. Le détecteur 7 est divisé en quatre quadrants permettant la production de deux signaux électriques de correction du mouvement d'image L'invention trouve son application dans les caméras embarquées sur avion.The subject of the invention is a device intended to stabilize the line of sight of a television camera mounted on a vehicle. The camera 1 is mounted, by elastic elements 2, on a surface 3 of the vehicle. The camera 1 carries a plane mirror 4 illuminated by an emitting diode 5 with a parallel beam formed by an auto-collimating lens 6. The light from the diode 5 is reflected by the mirror 4, this through the lens 6 and is focused on a detector 7. The movement of the vehicle causes the camera to rotate around the elements 2, relative to the reference plane 3. This movement is broken down into two orthogonal components 9 resulting in an angular error of the line of sight 8 which comes to occupy a new position 10. The detector 7 is divided into four quadrants allowing the production of two electrical signals for correcting image movement. The invention finds its application in cameras on board an airplane.
