Abstract

a. Système de balayage optique-mécanique pour dispositif de prise d'images embarqué sur satellite d'observation. b. Il comprend un système de deux miroirs qui reçoit du sol un faisceau portant l'image, le dévie et l'envoie sur un télescope et au moins un dispositif de synchronisation, et il est caractérisé en ce que le système des deux miroirs est formé de deux miroirs plans qui dévient successivement le faisceau et qui oscillent en sens opposé du même angle beta , les axes de rotation des miroirs étant parallèles entre eux et avec le vecteur vitesse du satellite, les miroirs étant montés sur des pivots de rotation et en ce que le dispositif de synchronisation comporte un émetteur d'un faisceau lumineux de synchronisation et un récepteur de ce faisceau et en ce que ledit faisceau de synchronisation subit de la part du systeme de deux miroirs au moins une fois la même déviation que le faisceau portant l'image. c. Observation de la terre par satellite.
