Abstract

TÊTE MATRICIELLE DE ROUTAGE DE FAISCEAUX LUMINEUX À ADRESSAGE FRÉQUENTIEL. L'INVENTION CONCERNE UN DISPOSITIF (FIG. 1) PERMETTANT DE GÉNÉRER UN FAISCEAU LUMINEUX MATRICIEL (1) ALIMENTANT, P.EX., LE DERNIER ÉTAGE D'UN ÉQUIPEMENT DE VIDÉO PROJECTION NUMÉRIQUE, À L'AIDE D'UNE COMBINAISON DE SOURCES LUMINEUSES (2), (3) ET (4) DE FAIBLE/MOYENNE PUISSANCE SUPPORTANT LES TROIS COULEURS DE BASE (LE ROUGE, VERT ET LE BLEU), DE TYPE LASER OU SOURCE AU XÉNON, ET DE N X M MIROIRS (5) D'UNE CERTAINE TAILLE ET FORME DÉFINIS EN FONCTION DE L'APPLICATION VISÉE, RÉALISANT LE FILTRAGE FRÉQUENTIEL APPROPRIÉ, LIÉ À LA CONSTRUCTION DU MIROIR. LE DISPOSITIF COMPORTE UN CERTAIN NOMBRE DE MATRICES (6), (7), (8) ET (9) DE MIROIRS/FILTRES ALIGNÉS GÉOMÉTRIQUEMENT, ORIENTANT ET FILTRANT LES FAISCEAUX LUMINEUX (10) DANS LE BUT DE GÉNÉRER UN ÉLÉMENT MATRICIEL/SYMBOLE (1) DE PROJECTION. LE DISPOSITIF S'AFFRANCHIT D'UNE FONCTION DE BALAYAGE GRÂCE À UN CODAGE FRÉQUENTIEL DE LA POSITION DE CHAQUE ÉLÉMENT MATRICIEL PROJETÉ. LA COMMANDE NUMÉRIQUE PERMET DE CONTRÔLER L'ALLUMAGE DES SOURCES LUMINEUSES EN FONCTION DE LA CONFIGURATION DE LA MATRICE/SYMBOLE D'AFFICHAGE RECHERCHÉ À UN INSTANT « T » DONNÉ. CETTE ÉLÉMENT MATRICIEL/SYMBOLE SERA BALAYÉ SUR UNE SURFACE DE PROJECTION AFIN DE GÉNÉRER UNE SÉQUENCE D'IMAGE VIDÉO COMPLEXE. LE SYSTÈME SERA APPLIQUÉ, P.EX. AU CINÉMA NUMÉRIQUE TRÈS HAUT DE GAMME ET AU « HOME CINÉMA ».
