An image scanning device is provided which includes a system for determining the distance to a target to be scanned. The image scanning device includes an optical system and an image sensor array for focusing a light beam and imaging the target. The device preferably includes an automatic focusing system for adjusting the position of the optical system in order to adjust the focal point, and thereby focus the image of the target onto the image sensor array. In one embodiment of the image scanning device, the distance is determined by analyzing a collimated aiming pattern formed by collimating the light beam. In another embodiment, the distance is determined by analyzing a speckle pattern caused by the speckle effect upon the light beam hitting the target.
L'invention concerne un dispositif de balayage d'images (12) qui comporte un système (404, 604) permettant de déterminer la distance (Zo) à une cible à balayer. Le dispositif de balayage d'images comporte un système optique et un réseau de capteurs d'images (403, 603) pour mettre au point un faisceau lumineux et imager la cible. Le dispositif comporte de préférence un système de mise au point automatique qui règle la position du système optique afin de régler le point focal, mettant ainsi au point l'image de la cible sur le réseau de capteurs d'images. Dans un mode de réalisation du dispositif de balayage d'images, on détermine la distance en analysant un motif de visée collimaté formé par collimation du faisceau lumineux. Dans un autre mode de réalisation, on détermine la distance en analysant un motif de tacheture dû au chatoiement lorsque le faisceau approprié touche la cible.
