Abstract: The general field provided is that of telescopes comprising an optical system and wavefront-analyzing placed in the focal plane of the optical system. The optical system comprises focusing optics and magnifying optics, the magnifying optics comprising a deformable mirror, the deformation of which is controllable. The telescope comprises monitoring the deformable mirror, comprising a source placed so that the image of the source, after reflection from the deformable mirror, is focused on the wavefront-analyzing. The monitoring comprises a movable mirror having two positions, a rest position and a monitoring position. The source may either be placed in the intermediate focal plane of the focusing optics, or at the focal point of a monitoring mirror, or even in the vicinity of the focal plane of the optical system.

Abstract: An optical monitoring device for an optical imaging system having a focal plane, an optical axis and an entry pupil, forming an image of a scene substantially at infinity on an image detector disposed substantially in the focal plane, comprises: a virtually point-like emission source at the periphery of the detector and substantially in the focal plane; a reflecting element with a plane surface upstream of the imaging system relative to the direction of light rays coming from the scene, and according to a position and inclination where a monitoring image of the source produced by the optical system and reflected by the reflecting element is substantially in the focal plane on a detection element connected to a monitoring image analyzer allowing potential optical defects to be identified; the reflecting element having an annular shape allowing passage of light rays coming from the scene and passing through the entry pupil.
