Claims (11)
- Appareil d'enregistrement d'image (14) configuré pour irradier une cible d'enregistrement (RL) à l'aide d'une lumière laser pour enregistrer une image, comprenant :une pluralité de parties d'émission de laser (41) qui sont disposées côte à côte dans une direction prédéterminée et qui sont configurées pour émettre de la lumière laser ;un système optique (43) qui est configuré pour collecter une pluralité de faisceaux de la lumière laser qui est émise par les parties d'émission de laser sur la cible d'enregistrement qui est déplacée par rapport aux parties d'émission de laser dans une direction qui croise la direction prédéterminée ; et caractérisé par :
une unité de commande de sortie (18) qui est configurée pour réaliser une commande de telle sorte que l'énergie de la lumière laser qui est émise depuis une partie d'émission de laser d'extrémité la plus externe des parties d'émission de laser soit plus importante que l'énergie de la lumière laser qui est émise depuis une partie d'émission de laser centrale, la partie d'émission de laser d'extrémité la plus externe émettant de la lumière laser destinée à être transmise au travers du voisinage d'une section d'extrémité du système optique, la partie d'émission de laser centrale émettant de la lumière laser destinée à être transmise au travers d'une section qui est autre que le voisinage de la section d'extrémité du système optique. - Appareil d'enregistrement d'image selon la revendication 1, comprenant en outre une pluralité d'unités de tête laser dont chacune inclut les parties d'émission de laser qui sont disposées côte à côte dans la direction prédéterminée, dans lequel :les unités de tête laser sont agencées en réseau dans la direction prédéterminée et sont disposées au niveau de positions qui sont différentes de celle d'une unité de tête laser adjacente dans la direction qui croise la direction prédéterminée ; etl'unité de commande de sortie réalise une commande de telle sorte que l'énergie de la lumière laser qui est émise depuis une partie d'émission de laser d'extrémité qui est positionnée au niveau d'une extrémité de l'unité de tête laser, à l'exclusion de la partie d'émission de laser d'extrémité la plus externe, soit plus importante que l'énergie de la lumière laser qui est émise depuis une partie d'émission de laser qui est autre que la partie d'émission de laser d'extrémité la plus externe et que la partie d'émission de laser d'extrémité.
- Appareil d'enregistrement d'image selon la revendication 2, dans lequel l'unité de commande de sortie commande l'énergie de la lumière laser qui est émise depuis la partie d'émission de laser d'extrémité, en fonction d'une vitesse de déplacement relative de la cible d'enregistrement.
- Appareil d'enregistrement d'image selon la revendication 3, comprenant en outre une unité de détection de température de cible d'enregistrement qui est configurée pour détecter la température de la cible d'enregistrement, dans lequel :
l'unité de commande de sortie commande l'énergie de la lumière laser qui est émise depuis la partie d'émission de laser en fonction d'un résultat de détection de l'unité de détection de température de cible d'enregistrement. - Appareil d'enregistrement d'image selon la revendication 3 ou 4, comprenant en outre une unité de détection de température d'environnement qui est configurée pour détecter la température de l'environnement, dans lequel :
l'unité de commande de sortie commande l'énergie de la lumière laser qui est émise depuis la partie d'émission de laser en fonction d'un résultat de détection de l'unité de détection de température d'environnement. - Appareil d'enregistrement d'image selon l'une quelconque des revendications 1 à 5, dans lequel l'unité de commande de sortie commande l'énergie de la lumière laser qui est émise depuis la partie d'émission de laser, sur la base de si la lumière laser est émise depuis une autre partie d'émission de laser qui est adjacente à la partie d'émission de laser.
- Appareil d'enregistrement d'image selon l'une quelconque des revendications 1 à 6, comprenant :une pluralité d'éléments d'émission de lumières laser qui sont configurés pour émettre de la lumière laser ; etune pluralité de fibres optiques qui sont disposées de manière à ce qu'elles correspondent aux éléments d'émission de lumière laser pour guider la lumière laser qui est émise depuis les éléments d'émission de lumière laser jusque sur la cible d'enregistrement, dans lequel :
la partie d'émission de laser est prévue pour chacune des fibres optiques. - Appareil d'enregistrement d'image selon la revendication 7, dans lequel l'unité de commande de sortie commande l'énergie de la lumière laser qui est émise depuis la partie d'émission de laser en fonction de la température de l'élément d'émission de lumière laser.
- Appareil d'enregistrement d'image selon la revendication 3, dans lequel l'unité de commande de sortie réalise une commande de telle sorte que l'énergie de la lumière laser qui est émise depuis la partie d'émission de laser qui est positionnée au niveau de l'extrémité ne soit pas inférieure à 103 % et ne soit pas supérieure à 150 % de l'énergie de la lumière laser qui est émise depuis l'autre partie d'émission de laser.
- Appareil d'enregistrement d'image selon l'une quelconque des revendications 1 à 9, comprenant en outre une unité de convoyage de cible d'enregistrement qui est configurée pour convoyer la cible d'enregistrement, dans lequel :
l'unité de commande de sortie permet que la partie d'émission de laser émette de la lumière laser pour enregistrer une image sur la cible d'enregistrement tout en permettant que l'unité de convoyage de cible d'enregistrement convoie la cible d'enregistrement. - Procédé d'enregistrement d'image réalisé dans un appareil d'enregistrement d'image (14) qui est configuré pour irradier une cible d'enregistrement (RL) à l'aide d'une lumière laser pour enregistrer une image, l'appareil d'enregistrement d'image comprenant :une pluralité de parties d'émission de laser (41) qui sont disposées côte à côte dans une direction prédéterminée et qui sont configurées pour émettre de la lumière laser ; etun système optique (43) qui est configuré pour collecter une pluralité de faisceaux de la lumière laser qui est émise par les parties d'émission de laser sur la cible d'enregistrement qui est déplacée par rapport aux parties d'émission de laser dans une direction qui croise la direction prédéterminée,le procédé étant caractérisé en ce qu'il comprend une étape de commande de sortie qui consiste à réaliser une commande de telle sorte que l'énergie de la lumière laser qui est émise depuis une partie d'émission de laser d'extrémité la plus externe des parties d'émission de laser soit plus importante que l'énergie de la lumière laser qui est émise depuis une partie d'émission de laser centrale, la partie d'émission de laser d'extrémité la plus externe émettant de la lumière laser destinée à être transmise au travers du voisinage d'une section d'extrémité du système optique, la partie d'émission de laser centrale émettant de la lumière laser destinée à être transmise au travers d'une section qui est autre que le voisinage de la section d'extrémité du système optique.
