摘要： An optical space observation system comprises a primary mirror, a secondary mirror, a supporting base containing the primary mirror, on which a mechanical structure bearing a support of the secondary mirror is positioned, and an optical measurement means, said mechanical structure comprising a plurality of mechanical arms. The system also has a system comprising a plurality of actuators positioned on the supporting base, said actuators being connected to the lower ends of said mechanical arms and the upper ends of said mechanical arms being connected to the support of the secondary mirror on the periphery of the support. A space telescope is intended to be loaded in a launcher and put into orbit. The invention is intended in particular for a telescope having a deployable secondary mirror and means for active control of the optics.

摘要： In the field of optical checking of optical instruments of telescope type, an instrument comprises an optical objective, a photo-detection housing arranged at the focus of said optical objective and at least one light source arranged in the vicinity of said photo-detection housing, the optical pupil of the optical objective having a first diameter. The checking means comprise a plane mirror having a second diameter that is smaller than the first diameter and means to arrange the plane mirror such that the image of the light source given by the optical objective and reflected by said plane mirror is focused on the photo-detection housing, means for analyzing said image received making it possible to determine the optical quality of the telescope. The plane mirror may be associated with an autonomous checking bench. It may also form part of the telescope and be incorporated into the protection hood for the optic.

摘要： A scanning multispectral telescope comprises an optical architecture arranged so as to focus the image of an object in the vicinity of a photodetection assembly, the area of focus being an image plane. The photodetection assembly comprises a number of parallel rows of photodetectors, each row being dedicated to a particular spectral band, each spectral band being centred on a mean wavelength. The telescope comprises means for acquiring and analyzing the images obtained from the rows of photodetectors using a phase diversity algorithm. Finally, the telescope comprises optical or mechanical means arranged in such a way that at least one of the rows of photodetectors is offset by a fraction of the mean wavelength which corresponds to it on an axis perpendicular to the image plane.
