摘要

A digital image capture and processing system including a housing having an imaging window. An area-type image formation and detection subsystem is disposed in the housing, and has image formation optics for projecting a field of view (FOV) through the imaging window and onto an area-type image detection array, for forming and detecting 2D digital images of an object in the FOV, during object illumination and imaging operations. The housing also includes a multi-mode LED-based illumination subsystem having (i) a near-field LED array for producing a field of wide-area narrow-band illumination over a near field region of said FOV, and (ii) a far-field LED array for producing a field of wide-area narrow-band illumination over a far field region of the FOV. During object illumination and imaging operations, illumination from illumination arrays reflects off the object and is transmitted back through the imaging window and onto the area-type image detection array to form 2D digital images of the object.
