摘要： A laser scanning bar code symbol reading system for scanning and reading poor quality or damaged bar code symbols. The system includes a housing having a light transmission window; an extremely-elongated laser beam production module for producing an extremely-elongated laser beam having (i) a direction of propagation extending along a z reference direction, (ii) a height dimension being indicated by the y reference direction, and (iii) a width dimension being indicated by the x reference direction, where x, y and z directions are orthogonal to each other. Each extremely-elongated laser beam is characterized by an elongation ratio (ER) that is defined as Y/X>4.5 for any point within the working range of the laser scanning bar code symbol reading system, extending along the z direction; where (i) Y indicates the beam height of the extremely-elongated laser beam measured in the Y reference direction, and X indicates the beam width of the extremely-elongated laser beam measured in the X reference direction, and (iii) the beam height (Y) and the laser beam width (X) are measured at 1/e2 intensity clip level. 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.
