Hand-supportable LED-based planar illumination and imaging system
First Claim
1. A hand-supportable planar 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
a plurality of planar illumination modules (PLIMs), arranged in a rectilinear manner and mounted on said support platform, along with said linear IFD module, and producing a planar 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 each said PLIM includes a visible light emitting diode (LED) and beam forming optics for producing said PLIB, where said beam forming optics includes a focusing lens and a beam planarizing lens;
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 images; and
a camera controller for controlling operations within said hand-supportable PLIIM based device.

Abstract
A hand-supportable planar illumination and imaging (PLIIM) based device having a hand-supportable housing with a light transmission aperture. A linear image formation and detection (IFD) module mounted on the support platform in the housing, and has a linear array of image detection elements and also image formation optics having a field of view (FOV) projectable through the light transmission aperture. When an object is presented in the FOV for illumination and imaging, the FOV focuses a linear image of the object onto the linear array of image detection elements. A plurality of planar illumination modules (PLIMs) are arranged in a rectilinear manner, and produce a planar illumination beam (PLIB) that is spatially aligned with respect to the FOV and arranged in a coplanar relationship with at least a portion of the FOV. Each PLIM includes a visible light emitting diode (LED) and beam forming optics for producing the PLIB.
