摘要： A telescope includes an initial telescope comprising a concave first mirror and a convex second mirror that are configured so that they form, from a light beam coming from infinity, an image called the intermediate image in a focal plane called the intermediate focal plane, the intermediate image having a largest dimension along an X-axis perpendicular to an optical axis of the telescope, a segmenting module comprising a first set of n segmenting mirrors that are placed downstream of the intermediate focal plane and that are configured to divide the intermediate image obtained from the intermediate focal plane into n sub-images, a second set of n refocusing mirrors that are configured to reimage the n sub-images into n images in a focal plane of the telescope, the images being arranged in the focal plane so as to decrease the dimension along X containing the n images, a detecting device placed in the focal plane.

摘要： An optical detector with a curved detection surface is provided, including a photosensitive sensor; a support imposing a curvature on the photosensitive sensor; and a glue layer, provided between the photosensitive sensor and the support, with a thickness higher than 50 μm. The glue layer with a high thickness enables requirements imposed on the sensor to be reduced, with an equal radius of curvature, and thus a minimum radius of curvature of the photosensitive sensor to be reduced, thereby compensating for significant defects of an imaging system located upstream.

摘要： A method of shaping an aspherical optical element is provided that includes the steps of fastening an optical element blank to a ring, the blank presenting an optical surface that is to be shaped and a surface referred to as a rear surface; applying forces and moments to the ring in order to deform the optical element and its optical surface, which element is fastened to the ring; using abrasion to shape said deformed optical surface so as to restore a spherical or planar shape thereto; and extracting the blank from the ring so as to release the stresses deforming said shaped optical surface so as to allow it to acquire the desired aspherical shape. The method also includes the step of fastening the blank to the ring is performed by bonding the optical surface or the rear surface to a surface of the ring with a layer of adhesive.
