Title:
BIOPTICAL LASER SCANNER FOR SIX-SIDED 360° POS-BASED SCANNING
Document Type and Number:
WIPO Patent Application WO2003057396
Kind Code:
A3
Abstract:
A bioptical laser scanning system (1) employing a plurality of laser scanning stations about a two independently controlled rotating polygonal mirrors. The system (1) has an ultra-compact construction (4A, 4B), ideally suited for space-constrained retail scanning environments, and generates a 3-D omnidirectional laser scanning pattern between the bottom and side-scanning windows (16,18) during system operation. The laser scanning pattern of the present invention comprises a complex of quasi-orthogonal laser scanning planes, including 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 bottom-scanning window (16), 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 bottom-scanning window (16).
