Abstract
A digital image capturing and processing system for use in retail point of sale (POS) environments. The system comprises a system housing having an imaging window, and a plurality of coplanar illumination and imaging stations mounted beneath the imaging window in the system housing. The stations generate and projects a plurality of coplanar illumination and imaging planes through the imaging window and into a 3D imaging volume definable relative to the imaging window. An imaging window protection plate is mounted over the imaging window and has an aperture pattern that corresponds to the plurality of coplanar illumination and imaging planes projected through the imaging window, so that the plurality of coplanar illumination and imaging planes are allowed to project through the aperture pattern and into the 3D imaging volume, while the imaging window protection plates protects the imaging window during system operation.
