Abstract

L'invention concerne une caméra de prise de vues électro-optique avec balayage (36) autour de l'axe de roulis, dans laquelle des clichés de scènes, successifs et se chevauchant, sont produits par un ensemble d'imagerie électro-optique. La compensation du déplacement d'image est réalisée électroniquement pour arrêter ou figer le déplacement d'image provoqué par le roulis. L'ensemble d'imagerie réalise cette compensation du déplacement d'image pendant la production des clichés d'imagerie. Ces clichés successifs sont réalisés au moment où la totalité de la caméra (y compris l'ensemble d'imagerie) exécute un mouvement de roulis continu. Le déplacement d'image dû au roulis est arrêté ou figé sans arrêt mécanique du roulis, à la différence des caméras à échelons de la technique antérieure. Les cycles de prises de vue de la caméra avec balayage autour de l'axe de roulis assurent la couverture par balayage du terrain à étudier. Le taux de roulis pour un ensemble électro-optique donné est fonction de la taille du cliché et de la cadence de prise de vues, et peut être régulé par un ordinateur pilote assurant la commande de la caméra. L'invention concerne également un nouveau système optique catoptrique Cassegrain qui assure une compensation du filé.
