摘要： Un dispositif produisant une sortie imprimée possède un réseau de sources lumineuses ponctuelles (26) focalisées sur une surface photosensible (22). Le réseau est espacé par rapport à la surface au niveau de la position du meilleur foyer en produisant une configuration de sources lumineuses activées et inactivées le long du réseau de sorte qu'une paire de sources lumineuses qui contribuent à la création d'une image sur la sortie sont séparées par une source lumineuse qui ne contribue pas à la création d'une image. Etant donné que la dimension de l'image croît en largeur au fur et à mesure que le foyer décroît, la largeur de l'espace entre les images peut être utilisée comme un calibre de focalisation, et des réglages appropriés peuvent être effectués pour maximiser la largeur de l'écartement.

摘要： An imaging device comprising a linear array (13) of laser diodes (16a-16f) that are adapted to provide an optical output comprising a plurality of spaced-apart optical beams (17a-17f). Focusing optics (18, 19) are configured to form a plurality of image points (7) from said spaced-apart optical beams, the image points being spaced apart along a first axis (7a). The image points have a non-uniform spacing (31, 41, 51, 52) along the first axis. By scanning the linear array along a photosensitive plate (5), and timing the firing of lasers accordingly, every pixel point on the photosensitive plate can be imaged by one of the image points from the laser array. Non-uniform spacing of the image points can provide advantages in heat dissipation from the laser elements, and reduction of some printing artifacts on the photosensitive plate.
