Abstract:
Near and far imagers image close-in and far-out targets over relatively wider and relatively narrower imaging fields of view, respectively. An aiming assembly directs to a target a visible aiming light pattern having an aiming light spot and a pair of collinear aiming light lines. The aiming light spot is substantially centered between the aiming light lines. A controller determines a distance to the target based on a position of the aiming light spot in the imaging field of view of a default one of the imagers, selects at least one of the imagers based on the determined distance, and enables both the close-in and the far-out targets to be positioned substantially entirely within the respective imaging field of view of the selected imager.
