ABSTRACT:
A bar code scanner comprises a radiant energy source for generating a radiant energy beam of a given configuration, a detector for generating output electrical signals indicative of radiant energy incident thereon, an optical system having a focus portion for transmitting segments of the radiant energy beam in separate optical paths extending from the scanner to a bar code to be scanned and a scan portion for collecting radiant energy transmitted by the focus portion as modified by the bar code and applying the same to the detector and a decoder for decoding the output electrical signals of the detector to provide indication of information contained in the bar code.
