Abstract:
1. A digital image capturing and processing system supporting pass-through and presentation modes of automatic digital imaging at a point of sale (POS) environment, comprising: a system housing having an imaging window with a surface; and a plurality of coplanar illuminating and imaging stations, disposed within said system housing, for generating a plurality of coplanar illumination and imaging planes that are projected through said imaging window and into a 3D imaging volume definable relative to said imaging window; wherein each said coplanar illumination and imaging station includes (i) an illumination subsystem having a linear illumination array including a plurality of light emitting devices for producing a planar illumination beam (PLIB), and (ii) an image formation and detection subsystem including a linear image sensing array having optics providing a field of view (FOV) on said linear image detection array, and extending substantially along said PLIB so as to form one said coplanar illumination and imaging plane (PLIB/FOV) that is projected through said imaging window and into said 3D imaging volume, for capturing linear (ID) digital images of objects moving through said 3D imaging volume, and subsequent processing to read information graphically represented in said linear digital images; wherein said plurality of coplanar illumination and imaging planes are spatially arranged with respect to said imaging window so as to enable both said pass-through and presentation modes of automatic digital imaging at said POS environment.
