1. An automatic hand-supportable laser scanning bar code reading system comprising:

  • a first omni-directional bar code reading mode of operation, wherein a visible omni-directional laser scanning pattern produces multiple laser scanning lines having substantially uniform spatial and temporal intensity characteristics in any given scanning plane for the purpose of scanning and reading bar code symbols; and

    a second uni-directional bar code reading mode of operation, wherein against a visible stroboscopically-pulsed omni-directional laser scanning pattern, there is produced a single laser scanning line having substantially uniform spatial and temporal intensity characteristics in any given scanning plane for the purpose of scanning and reading bar code symbols.
