Abstract
A hand-supportable planar linear illumination and imaging (PLIIM) based code symbol reading system comprising: a hand-supportable housing having a light transmission aperture; and a planar laser illumination and imaging module (PLIIM), disposed in the hand-supportable housing. The PLIIM includes (i) a linear image detection array having optics providing a field of view (FOV) on said linear image detection array that projects through the light transmission aperture, and (ii) at least one planar laser illumination module (PLIM) for producing a substantially planar laser illumination beam (PLIB) that extends substantially along the same plane as the FOV of the linear image detection array. This arrangement provides a coplanar illumination and imaging plane that projects through the light transmission aperture, for capturing a series of linear (1-D) digital images of an object intersecting therewith during object illumination and imaging operations. An image frame grabber then accesses 1-D digital images therefrom and composes a 2-D digital image of the object. An image data buffer buffers 2-D images received from the image frame grabber, and a decode image processor processes the digital images stored within the image data buffer so as to read one or more code symbols graphically represented in the digital images. A system controller controls the operations within the system.
