Title (EN) LARGE FORMAT LASER SCANNER WITH WAVELENGTH INSENSITIVE SCANNING MECHANISM
(FR) DISPOSITIF DE BALAYAGE AU LASER DE GRAND FORMAT DOTE D'UN MECANISME DE BALAYAGE INSENSIBLE AUX LONGUEURS D'ONDE
Abstract:
(EN) A large format laser scanning system is disclosed that incorporates a compact, wobble free and wavelength insensitive scanning mechanism. The scanning mechanism includes a pentaprism and lens mounted on a rotating frame assembly that is located within a scanning drum. Multiple light beams generated by a light source are passed through the rotating pentaprism and lens to scan a photosensitive medium located on the interior surface of the scanning drum.
(FR) Système de balayage au laser de grand format comprenant un mécanisme de balayage compact, exempt de vacillations et insensible aux longuers d'onde. Ledit mécanisme de balayage comporte un prisme pentagonal et une lentille montés sur un cadre rotatif situé à l'intérieur du tambour de balayage. Des faisceaux de lumière multiples engendrés par une source lumineuse sont envoyés à travers le prisme pentagonal rotatif et la lentille de manière à balayer un support photosensible situé sur la surface interne du tambour de balayage.
