Abstract
A system for scanning human or machine readable information located on objects moving in a transport direction along a transport path. An imaging device having a first observation path and at least a 1×N sensor array is also provided. A scanning zone is located along the transport path. A rotating sweeping unit is positioned to receive light from the scanning zone and reflect it to the imaging device. The sweeping unit sweeps through the scanning zone along a sweep path. The imaging device captures a plurality of image segments that extend generally across the transport path and are each at least 1×N pixels in size. Movement of the sweeping unit is preferably synchronized to movement of the objects along the transport path.
