  • Cassegrain telescope with a segmented focal plane
    Patent number: 11480806
    Abstract: 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.
