Abstract:
The system includes a housing having a light transmission window and produces an extremely-elongated laser beam having an elongation ratio (ER) that is defined as greater than 4.5 for any point within the working range of the laser scanning bar code symbol reading system. A laser scanning mechanism is provided for scanning the extremely-elongated laser beam out the light transmission window and across a scanning field defined external to the housing, in which a bar code symbol is present for scanning by the extremely-elongated laser scanning beam.
