Abstract
An aiming pattern is used with an automatic focusing system for an imaging-based bar code reader. The combination of the thick horizontal line and the thin vertical line yields an aiming pattern that can be effectively used for ranging purposes while at the same time providing sufficient illumination for decoding 1-D barcodes.
