Abstract

A scanner system is operable for gathering graphic data from a scan target. The scanner system has a single illumination source component operable for generating light, for aiming the scanner system with a filtered beam of the generated light directed at the scan target, and for illuminating the scan target with the directed light. The scanner system also has a detector component operable for sensing a reflection from the scan target, the sensed reflection including a portion of the directed light with which the scan target is illuminated, and for detecting information in the sensed reflection, in which the information detected in sensed reflection corresponds to the graphic data gathered from the scan target.
