A method of illuminating objects using adaptively controlled mixing of spectral illumination energy to form and detect digital images of objects at POS environments with sufficiently high image contrast and quality. The method comprises providing, at a POS environment, a digital image capture and processing system having a system housing with an imaging window, and a coplanar illumination and imaging station disposed within said system housing, for projecting a coplanar illumination and imaging plane through the imaging window into an imaging volume during object illumination and imaging operations. As the object is moved through the imaging volume, its motion is automatically detected, and signals indicative of said detected object are generated. In response to the generated signals, a first field of visible illumination is produced from an array of visible laser diodes (VLDs), simultaneously with a second field of invisible illumination from a array of infrared (IR) laser diodes (LDs). These first and second fields of illumination spatially overlap and intermix with each other and produce a composite planar illumination beam that is substantially coextensive with the FOV.

A digital image capturing and processing system including an image formation and detection (IFD) subsystem having a linear image sensing array and optics providing a field of view (FOV) on the linear image sensing array. A spectral-mixing based illumination subsystem produces a first field of visible laser illumination produced from an array of visible VLDs, and a second field of invisible laser illumination produced from an array of IR laser diodes (LDs) that spatially overlap and intermix with each other so as to produce a composite planar laser illumination beam which is substantially with the FOV of the linear image sensing array. An illumination control subsystem controls the spectral mixing of visible and invisible laser illumination produced from the spectral-mixing based illumination subsystem, by adaptively controlling the relative power ratio (VIS/IR) of said fields of visible and invisible laser illumination. An image capturing and buffering subsystem captures and buffers images from the image sensing array. An automatic object detection subsystem automatically detects the an object moving through at least a portion of the FOV of the linear image sensing array, and generation a control activation signal.

A method of illuminating objects using adaptively controlled mixing of spectral illumination energy to form and detect digital images of objects at a POS. The method comprises providing, at a POS environment, a digital image capture and processing system having a system housing with an imaging window, and an area-type illumination and imaging station disposed within said system housing, for projecting a coextensive area-type illumination and imaging field (i. e. zone) through said imaging window into a 3D imaging volume during object illumination and imaging operations. As the object is moved through the 3D imaging volume, its motion is automatically detected, and signals indicative of said detected object motion are generated. In response to the generated signals, a first field of visible illumination is produced from an array of visible LEDs, simultaneously with a second field of invisible illumination from a array of infrared (IR) LEDs. These first and second fields of illumination spatially overlap and intermix with each other to produce a composite wide-area illumination beam that is at least substantially coextensive with the FOV.

A coplanar laser illumination and imaging subsystem deployable in an image capturing and processing system, and including an image formation and detection (IFD) subsystem having an image sensing array and optics providing a field of view (FOV) on the image sensing array, and forming an image of an object within the FOV and detecting said image on the image sensing array and producing a digital image thereof. The system includes a spectral-mixing based illumination subsystem having an array of VLDs for producing a visible illumination beam, and an array of infrared (IR) laser diodes (LDs) for producing an invisible illumination beam. The visible and invisible illumination beams spatially overlaps and spatially/temporally intermixes with each other to produce a composite spectrally-mixed illumination beam having a relative power ratio of visible illumination to invisible illumination (VIS/IR), and is substantially coplanar with the FOV of said image sensing array. A laser despeckling mechanism is provided for reducing the coherence of the composite spectrally-mixed illumination beam, and/or its components, so that the digital images produced by the IFD subsystem having substantially reduced levels of speckle-pattern noise when the laser despeckling mechanism is operational.

A digital illumination and imaging system employing one or more planar laser illumination modules (PLIMs) each including: (i) a laser illumination source driven preferably by high frequency modulated (HFM) diode current drive circuitry; (ii) a beam collimating optics disposed beyond the laser source; (ii) an optical beam multiplexer (OMUX) device disposed beyond the collimating optics; and (iv) a planarizing-type illumination lens array disposed beyond the OMUX device, and arranged for generating a plurality of substantially planar coherence-reduced laser illumination beams (PLIBs) that form a composite substantially planar laser illumination beam (PLIB) having substantially reduced spatial/temporal coherence. A digital image detection array for detecting digital images of an object illuminated by the composite substantially planar laser illumination beam. By virtue of the present invention, the power of speckle pattern noise, observed in a digital image of an object detected at the digital image detection array, is substantially reduced when the digital image is formed using the substantially planar laser illumination beam.

A POS-based digital image capturing and processing system for illuminating objects using automatic object detection and spectral-mixing illumination technique. The system comprises an area-type illumination and imaging station for projecting a coextensive area-type illumination and imaging field (i. e. zone) into a 3D imaging volume during object illumination and imaging operations. The area-type illumination and imaging station includes an illumination subsystem for producing a first field of visible illumination from an array of visible LEDs, and producing a second field of invisible illumination from an array of infrared (IR) LEDs. wherein the first and second fields of illumination spatially overlap and intermix with each other and are substantially coextensive with the FOV of the image sensing array. An automatic object motion detection subsystem automatically detects the motion of an object moving through the 3D imaging volume, while an illumination control subsystem controls the relative power ratio (VIS/IR) of visible illumination and invisible illumination during system operation so as to minimize the amount of visible illumination energy required to capture sufficiently high-contrast images of said objects and successfully process the same.
