Abstract: 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.

Abstract: An optical scanning system of the type in which an oscillating mirror (14) is provided to scan the optical axis (12) of a focusing lens (10) across a flat field (16), wherein the optical axis (18) of the mirror is translated during oscillation of the mirror. The pivot axis (18) of the mirror is translated at an angle of 45° with respect to the optical axis of the focusing lens thereby enabling the mirror to be translated at a uniform velocity during scanning to provide a uniform velocity scan.

Abstract: 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.

Abstract: On décrit un système d'exploration optique du type pourvu d'un miroir oscillant (14) servant à explorer un champ plat (16) par le déplacement de l'axe optique (12) d'une lentille de focalisation (10), et dans lequel l'axe optique (18) du miroir est translaté au cours de l'oscillation du miroir. L'axe de pivotement (18) du miroir est translaté à un angle de 45° par rapport à l'axe optique de la lentille de focalisation, ce qui permet au miroir d'être translaté à une vitesse uniforme au cours de l'exploration pour permettre une exploration à vitesse uniforme.
