Abstract
Disclosed is a bioptical laser scanning system that provides 360° of omnidirectional bar code symbol scanning coverage at a point of sale (POS) station. The system generates a 3-D omnidirectional laser scanning pattern between the horizontal and vertical scanning windows during system operation. The laser scanning pattern of the present invention comprises a complex of pairs of quasi-orthogonal laser scanning planes, each composed by a plurality of substantially-vertical laser scanning planes for reading bar code symbols having bar code elements (i.e. ladder-type bar code symbols) that are oriented substantially horizontal with respect to the horizontal scanning window, and a plurality of substantially-horizontal laser scanning planes for reading bar code symbols having bar code elements (i.e. picket-fence type bar code symbols) that are oriented substantially vertical with respect to the horizontal scanning window.
