Title
(EN) PORTABLE DEVICE FOR ANALYSING A PLURALITY OF WIDELY SPACED LASER BEAMS
(FR) DISPOSITIF PORTABLE POUR ANALYSER UNE PLURALITÉ DE FAISCEAUX LASER LARGEMENT ESPACÉS
Abstract
(EN)
A system and method for performing field measurement and testing of a plurality of widely spaced laser beams used in visual warning technology (VWT). VWT uses a combination of widely spaced laser beams, to warn civilians from approaching too close to military security areas. The widely spaced laser beams are displaced using rhomboidal prisms. Each rhomboidal prism receives a corresponding laser beam and displaces it toward a collecting lens. The lens focuses the displaced beams received thereon onto an imaging sensor for testing. Beam shutters may be used for selectively blocking one or more beams in order to test the beams separately and in different combinations.
(FR)
La présente invention porte sur un système et un procédé pour réaliser une mesure de champ et tester une pluralité de faisceaux laser largement espacés utilisés dans une technologie d'avertissement visuel (VWT). VWT utilise une combinaison de faisceaux laser largement espacés, pour prévenir des civils s'approchant trop près de zones de sécurité militaire. Les faisceaux laser largement espacés sont déplacés à l'aide de prismes rhomboïdaux. Chaque prisme rhomboïdal reçoit un faisceau laser correspondant et le déplace vers une lentille de collecte. La lentille focalise les faisceaux déplacés reçus sur celle-ci sur un capteur d'imagerie pour essai. Des obturateurs de faisceau peuvent être utilisés pour bloquer de manière sélective un ou plusieurs faisceaux afin de tester les faisceaux séparément et en différentes combinaisons.
