Abstract
(EN) The invention relates to an optical device (40) for obtaining an enlargement of a given area of a 360° panoramic field of view, which is applicable to an optical system (20) for obtaining a 360° panoramic field of view, which comprises a retro-reflector (3) with an outer convex spherical surface (1) and an image sensor (18) for digital processing the field of view; the optical device (40) comprises a magnifying optical element (6), which is fixable to the retro-reflector (3) in correspondence with the outer convex spherical surface (1), and deflector means (19) able to catch the rays coming from a given area of the 360° panoramic field of view and to re-transmit the rays toward the optical element (6); the optical element (6) transmits the rays to the image sensor (18). The invention also relates to an optical system (20) comprising said optical device (40), an apparatus for filming the images and an apparatus for projecting the images comprising said optical system (20).
(FR) La présente invention concerne un dispositif optique (40) qui permet d'obtenir un agrandissement d'une zone donnée d'un champ de vision panoramique à 360°, et qui peut être utilisé dans un système optique (20) afin d'obtenir un champ de vision panoramique à 360°, ce système optique (20) comprenant un rétroréflecteur (3) doté d'une surface sphérique convexe extérieure (1) ainsi qu'un capteur d'image (18) pour le traitement numérique du champ de vision. Le dispositif optique (40) comporte un élément optique de grossissement (6) qui peut être fixé sur le rétroréflecteur (3) de manière à correspondre à la surface sphérique convexe extérieure (1), et un moyen déflecteur (19) pouvant capter les rayons en provenance d'une zone donnée du champ de vision panoramique à 360° et retransmettre ces rayons vers l'élément optique (6). Ledit élément optique (6) transmet les rayons au capteur d'image (18). La présente invention se rapporte également à un système optique (20) qui comprend ledit dispositif optique (40), à un appareil conçu pour filmer les images, ainsi qu'à un appareil prévu pour projeter les images et comportant ce système optique (20).
