| 1. A digital image capturing and processing system for use in retail point of sale (POS) environments, comprising:
a system housing having an imaging window;
a plurality of coplanar illumination and imaging stations mounted beneath said imaging window in said system housing, for
generating and projecting a plurality of coplanar illumination and imaging planes through said imaging window and into a 3D
imaging volume definable relative to said imaging window; and
an imaging window protection plate mounted over said imaging window and having an aperture pattern that corresponds to said
plurality of coplanar illumination and imaging planes projected through said imaging window, so that said plurality of coplanar
illumination and imaging planes are allowed to project through said aperture pattern and into said 3D imaging volume, while
said imaging window protection plates protects said imaging window during system operation;
wherein said aperture pattern includes a central X aperture pattern and a pair of parallel apertures aligned parallel to the
sides of the system housing, and said plurality of said coplanar illumination and imaging planes are configured to project
through said central X aperture pattern and said pair of parallel apertures.
