1. A hand-supportable planar laser illumination and imaging (PLIIM) based device, comprising:

  • a hand-supportable housing having a light transmission aperture;

    a support platform mounted within said hand-supportable housing;

    a linear image formation and detection (IFD) module mounted on said support platform, and having a linear array of image detection elements and also image formation optics having a field of view (FOV) projectable through said light transmission aperture and into an illumination and imaging field, definable external to said hand-supportable housing, and in which an object can be presented for illumination and imaging, and said FOV focusing a linear image of said object onto said linear array of image detection elements, and said linear array of image detection elements detecting a linear image of said object; and

    at least one planar laser illumination module (PLIM) mounted on said support platform, along with said linear IFD module, and producing a planar laser illumination beam (PLIB) that is spatially aligned with respect to said FOV and arranged in a coplanar relationship with at least a portion of said FOV;

    wherein said PLIM includes a visible laser diode (VLD) and beam forming optics for producing said PLIB;

    an image frame grabber for grabbing linear digital images formed and detected by said linear IFD module;

    an image data buffer for buffering said grabbed linear digital images;

    an image processor operably associated with said image data buffer, for processing said buffered linear digital images; and

    a camera controller for controlling operations within said hand-supportable PLIIM based device.
