An optical system for observing an object from numerous sighting axes, comprising an optical instrument with an optical axis and a rotating mirror adapted to intercept a beam emitted or received by the instrument, depending on the optical axis. The rotating mirror has an axis of rotation and two back-to-back reflective surfaces that are at least approximately perpendicular to the plane containing the axis of rotation. At least one of the reflective surfaces has a non null angle of inclination relative to this axis of rotation. The optical system has different sighting axes, depending upon which of the reflective surfaces is intercepted by the optical axis of the optical instrument.
Un système optique pour l'observation d'un objet selon une pluralité d'axes de visée, comportant un instrument optique ayant un axe optique et un miroir rotatif adapté à intercepter un faisceau émis ou reçu par l'instrument selon cet axe optique, ce miroir rotatif ayant un axe de rotation et comportant deux surfaces réfléchissantes disposées dos à dos en étant au mois approximativement prependiculaires à un même plan contenant l'axe de rotation, l'une au moins des surfaces réfléchissantes ayant une inclinaison non nulle par rapport à cet axe de rotation, le système optique ayant des axes de visée différents selon que l'axe optique de l'instrument optique intercepte l'une ou l'autre des surfaces réfléchissantes.
