Abstract
A bioptical laser scanning system employing a plurality of laser scanning stations about a two independently controlled rotating polygonal mirrors. The system has an ultra-compact construction, ideally suited for space-constrained retail scanning environments, and generates a 3-D omnidirectional laser scanning pattern between the bottom and side-scanning windows during system operation. The laser scanning pattern of the present invention comprises plurality of groups of intersecting laser scanning planes that form a complex omni-directional 3-D laser scanning pattern within a 3-D scanning volume capable of scanning a bar code symbol located on the surface of an object presented within the 3-D scanning volume at any orientation and from any direction at the POS station so as to provide 360.degree. of omnidirectional bar code symbol scanning coverage at the POS station.
