ABSTRACT:
A bar code reader and method of reading a bar code symbol successively generates scan patterns at different times on the symbol. Preferably, two light sources are alternately energized to alternately produce two scan lines across the symbol. Each scan line reflects light from the symbol. The reflected light is detected by a photodetector which, in turn, generates an electrical signal. This signal is decoded into data corresponding to the symbol.
