Abstract: A device for optically multiplexing a laser beam, having a glass plate construction with an input surface and an output surface, and bearing reflective and semi-reflective coatings arranged so as to optically multiplex an input laser beam entering the input surface, into multiple spatial-coherence reduced output laser beams exiting from the output surface. Through such optical multiplexing, and recombination, the coherence of the resulting laser beam is substantially reduced, as is the power of speckle pattern noise observed at an image detection array detecting an image of an object illuminated by said laser beam.

Abstract: 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. During object illumination and imaging operations, the relative power ratio (VIS/IR) of these fields of visible illumination and invisible illumination is adaptively controlled as one or more digital images of the illuminated object are formed and detected, captured and buffered, and ultimately processed so as to read one or more 1D and/or 2D code symbols graphically represented in the digital images.

Abstract: A method of determining the lower limit of decoding resolution in a digital imaging-based bar code symbol reader. A software-based optical design program is used to generate the composite DOF chart of image formation optics employed in the digital imaging-based bar code symbol reader. The modulation transfer function (MTF) of the object image is used to determine the smallest mil size code that can be decoded, at a given object distance, to produce an optical performance curve. The program calculates the size of the field of view (FOV) of a single sensor pixel, when projected through the image formation optics and out into object space. For both the 1.4 and 1.6 sampling limit pixel rules, the calculated FOV values are plotted on the same axes as the optical performance curve. Using graphical solution techniques, the sampling limit line of choice determines the lower limit of the decoding resolution in the imaging-based bar code symbol reader.

Abstract: A digital image capturing and processing system comprising a plurality of coplanar illumination and imaging stations for producing a plurality of coplanar linear illumination and imaging planes which intersect within a 3D imaging volume defined relative to an imaging window. Each station includes an array of planar illumination modules (PLIMs) for producing at least one substantially planar illumination beam (PLIB), and a linear image detection array having a field of view (FOV) on the linear image detection array and extending in substantially the same plane as the PLIB, to provide a coplanar illumination and imaging plane (PLIB/FOV). The PLIB/FOV is projected through the 3D imaging volume, for capturing linear (1D) digital images of an object passing therethrough, for subsequent processing and recognition of information graphically represented in the linear digital images. Each station also employs a local control subsystem for controlling at least one illumination parameter associated with the production of the PLIB, in response to the motion and velocity of objects detected within the 3D imaging volume during system operation. By virtue of the present invention, it is possible to optimally illuminate objects based on the velocity at which such objects pass through the 3D imaging volume, at point-of-sale (POS) stations and like retail environments. Such illumination control ensures the capture of high quality digital images of objects, resulting in improved image processing.

The vertical housing section has a vertical imaging window, and contains a second plurality of coplanar illumination and imaging stations for generating and projecting second group of coplanar illumination and imaging planes through the vertical imaging window, which intersect with the first group of coplanar illumination and imaging planes and the area-type illumination and imaging zone, within a 3D imaging volume definable relative to the horizontal and vertical imaging windows, for omni-directional digital imaging of the object passing through the 3D imaging volume. Digital linear images of the object are generated as the object intersects the coplanar illumination and imaging planes, and digital area-type digital images of the object are generated as the object intersects with the area-type illumination and imaging zone, within the 3D imaging volume during system operation.
