Compact bar code symbol reading system employing a complex of coplanar illumination and imaging stations for omni-directional imaging of objects within a 3D imaging volume

摘要

An omni-directional bar code symbol reading system employing a plurality of coplanar illumination and imaging stations for generating and projecting a complex of coplanar illumination and imaging planes through an imaging window into a 3D imaging volume, through which object can be passed in flexible ways. The system has an ultra-compact construction, ideally suited for space-constrained retail scanning environments, and requires no moving parts.
