Abstract
A system and method are presented for improving the performance of full range code scanners. A distance detection module determines the distance of the code symbol from the code symbol reader. In response to the detected distance, the sweep angle of the scanning element is changed to ensure that the code symbol is within the code symbol reader's field of view. The sweep angle is larger when the code symbol is in the near range, and smaller when the code symbol is in the far range.
