Abstract
(EN)
Engine for video projection/digitiser/digital radar with multiple electromagnetic radiation beams for carrying out the projection or recording in 2D or 3D on any surface or in any volume. The invention relates to an optical digital video projection device for multi beam projection onto any surface or into any volume in 2D or 3D, within a solid angle from 0° to 360°, for example, 180, 270, or 360°. The device can also be used in digitiser and/or radar function for the recording/digitisation of spatial and frequency information. The processing of electromagnetic radiation, for example, visible, infrared ultraviolet, microwave radiation in time, space and frequency either passively or actively for example, by means of mirror/filter windows permits a filter function specific to the target applications. The source uses a light source comprising, for example, a number of weak/medium/high power lasers coupled to a number of optical sources, optical source modules, coloured beam generators or optical matrix heads. The digitisation function uses, for example, a number of photodiode capture devices, charge coupled devices (CCD), etc. The function for digitisation/optical radar in 2D or 3D using light beams permits use in different types of application, in telecommunications, for road maritime, aerial or space navigation.

Moteur de vidéo projection/Numériseur/Radar numérique à balayage multifaisceaux électromagnétiques, réalisant la projection ou capture, 2D/3D, sur une surface ou dans un volume quelconque(s). L'invention concerne un dispositif de vidéo projection numérique optique permettant la projection multifaisceaux sur une surface et / ou dans un volume quelconque(s) en 2D/3D, à l'intérieur d'un angle solide de 0° à 360°, p.ex. de 18072707360°. Ce dispositif peut aussi être utilisé en fonction numériseur et / ou radar pour la capture/numérisation d'informations spatiales et fréquentielles. Le traitement des faisceaux électromagnétiques, p.ex. visible, infrarouge, ultraviolet, micro-onde au niveau temporel, spatial et fréquentiel de type passif et actif, p.ex. à l'aide de fenêtres miroirs/filtres permet de réaliser une fonction de filtrage spécifique en fonction des applications visées. Le dispositif utilise, p.ex. comme source lumineuse un certain nombre de lasers de faible / moyenne / haute puissance, couplé à un certain nombre de sources optiques, de modules sources optiques, de générateurs de faisceaux colorés ou de têtes matricielles optiques. La fonction numérisation utilise, p.ex. un certain nombre de dispositif de capture de type photodiodes, dispositif à transfert de charge (CCD),... La fonction de numérisation/radar optique 2D/3D à base de faisceaux lumineux en autorise l'utilisation dans différents domaines d'applications en télécommunication, au niveau de la navigation routière, maritime, aérienne ou spatiale.
