Abstract

An digital image capturing and processing system comprising a plurality of coplanar illumination and imaging stations projecting a complex of coplanar illumination and imaging planes into a 3D imaging volume so as to support pass-through and presentation modes of digital imaging at a point of sale (POS) environment. Each station includes an illumination subsystem having a linear illumination array including a plurality of light emitting devices for producing a planar illumination beam (PLIB), and an image formation and detection subsystem including a linear image sensing array having optics providing a field of view (FOV) on the linear image detection array, and extending substantially along the PLIB. A plurality of coplanar illumination and imaging planes (PLIB/FOVs) are formed and projected through the imaging window and into the 3D imaging volume, for capturing linear (1D) digital images of objects moving through the 3D imaging volume. Each station includes an automatic illumination control subsystem for controlling the production of illumination by the illumination subsystem into the 3D imaging volume, as an object is detected moving within the 3D imaging volume.
