Patent number: 11703386Abstract: Disclosed is an instrument including a multipath, monolithic optical component, made up of a portion of a transparent material between two opposite faces of the component. One of the two faces of the component is formed by a first refracting surface, and the other face includes several second refracting surfaces which are juxtaposed. Each optical path of the component is formed by one of the second refracting surfaces in combination with a corresponding portion of the first refracting surface. One such component is suited for being part, within the instrument, of a detection module with multiple optical paths arranged in parallel, with a matrix photodetector shared by the optical paths. Such a detection module may be compact enough in order to be integrated into a cryostat cold screen, improving cooling thereof, and may be combined with an objective in order to form an instrument with multiple optical paths.Type: GrantFiled: December 13, 2019Date of Patent: July 18, 2023Assignee: OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AÉROSPATIALESInventors: Guillaume Druart, Florence De La Barriere

Patent number: 9316541Abstract: The imaging system for imaging field rays comprises a detection surface, a device for focusing the field rays with said detection surface, and a diaphragm. Said device comprises a Fresnel lens comprising a first dioptre, the non-plane surface of which, called the active zone, makes it possible to focus the field rays towards said detection surface, and said diaphragm allows controlled distribution of the field rays over said active zone.Type: GrantFiled: April 16, 2012Date of Patent: April 19, 2016Assignees: OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES (ONERA), ULISInventors: Guillaume Druart, Florence De La Barriere, Arnaud Crastes
