摘要： A method of and system for automatically identifying packages during manual package sortation operations, wherein, a laser scanning system is supported above a workspace environment of 3-D spatial extent, which is occupied by a human operator involved in the manual sortation of packages bearing bar code symbols. In the illustrative embodiment, the laser scanning system includes a housing having a light transmission aperture, and a laser scanning pattern generator disposed within the housing. During operation of the system, the laser scanning pattern generator employs a holographic scanning disc to project through the light transmission aperture, an omnidirectional laser scanning pattern which is substantially confined within the spatial extent of a predefined 3-D scanning volume that spatially encompasses a substantial portion of the workspace environment occupied by the human operator, through which packages are transported during sorting operations. As each package bearing a bar code symbol is transported through the workspace environment occupied by the human operator the package is automatically identified by the laser scanning system supported above the workspace environment. Thereafter, the package is manually sorted by the human operator working beneath the laser scanning system. By virtue of the present invention, bar coded packages can now be automatically identified as a human operator manually sorts the same within the allocated workspace environment, while improving package sortation accuracy and worker productivity.

摘要： A laser scanning system capable of producing information specifying the subregion of space within a 3-D scanning volume within which a bar code symbol is detected by a laser scanning pattern. The system comprises a laser scanning pattern generator, a scan data processor, a bar code symbol position data generator and a system controller. In the illustrative embodiment, the laser scanning pattern generator employs a holographic scanning disc to generate an omnidirectional laser scanning pattern within the 3-D scanning volume for scanning a bar code symbol presented therein, and in response thereto, automatically produces scan data indicative of the scanned bar code symbol. The scan data processor automatically processes the produced scan data so as to detect the scanned bar code symbol within the 3-D scanning volume. The bar code symbol position data generator automatically determines a subregion of space within the 3-D scanning volume wherewithin the detected bar code symbol is scanned by the laser scanning pattern, and automatically produces bar code symbol position data indicative of this subregion of space. By virtue of the present invention, it is now possible to generate, on a real-time basis, information specifying the position of a detected bar code symbol anywhere within the prefined 3-D scanning volume of a laser scanning system.

摘要： A holographic laser scanning system for scanning bar code symbols and the like, comprising: a holographic scanning disc; a plurality of laser beam sources; a plurality of beam folding mirrors adjacent the holographic scanning disc; a plurality of light focusing elements disposed beneath the holographic scanning disc; and plurality of photodetectors disposed above the holographic scanning disc. The light focusisng elements below the holographic scanning disc focus reflected laser light collected through the elements of the holographic scanning disc and retransmit the same therethrough off Bragg for direct detection by the photodetectors which are proximately dispposed to and above the holographic scanning disc. Several important advantages are obtained by providing light collection optics disposed below the holographic scanning disc, and retransmitting focused/collected laser light through the holographic scanning disc at an angle substantially off a Bragg angle of about 44 degrees. In particular, it is now possible to design and construct holographic laser scanners employing miultiple laser scanning stations within compact scanner housings having minimized height dimensions, while avoiding interference among the multiple outgoing, incoming and retransmitted laser beams generated within the scanner housing during laser scanning and light collection operations.

摘要： A code symbol reading system comprising first and second scanners. The first scanner employs a holographic scanning disc to generate an omnidirectional laser scanning pattern within a large 3-D scanning volume. The first scanner detects the location of a code symbol within the 3-D scanning volume and produces data indicative of its location therewithin. Using this location data, the second scanner produces a high density scanning pattern to aggressively scan the region in which the code symbol has been detected, and collect scan data for decode processing. By virtue of the system and method of the present invention, it is now possible to read bar code symbols located anywhere within very large volume of space, with a high degree of accuracy hitherto impossible using prior art techniques.

摘要： A fully automated package identification and measuring system, in which an omni-directional holographic scanning tunnel is used to read bar codes on packages entering the tunnel, while a package dimensioning subsystem is used to capture information about the package prior to entry into the tunnel. Mathematical models are created on a real-time basis for the geometry of the package and the position of the laser scanning beam used to read the bar code symbol thereon. The mathematical models are analyzed to determine if collected and queued package identification data is spatially and/or temporally correlated with package measurement data using vector-based ray-tracing methods, homogeneous transformations, and object-oriented decision logic so as to enable simultaneous tracking of multiple packages being transported through the scanning tunnel.

摘要： A holographic laser scanning system for carrying out laser beam scanning operations with improved light collection efficiency. The holographic laser scanning system comprises: a housing of compact construction; a plurality of laser beam sources; a holographic scanning disc supporting a plurality of holographic optical elements having fringe structure of variable spatial frequency; a plurality of laser beam folding mirrors disposed about the holographic scanning disc; a plurality of light focusing surfaces disposed below the holographic scanning disc; and a plurality of photodetectors disposed at the focal points of the light focusing surfaces. During laser beam scanning operations, each laser beam is transmitted through the outer edge portion of each holographic optical element at an angle of incidence. During light collection operations, a portion of the laser light rays reflected off a code symbol scanned by a produced laser scanning plane is collected over the total surface area of the holographic optical element producing the laser scanning plane. The collected laser light rays are focused by the light focusing surface to the respective photodetector, for detecting the intensity of the focused laser light rays for detection and generation of a scan data signal for subsequent processing. By virtue of the system of the present invention, light collection operations are carried out with improved light collection efficiency.

摘要： The first scanner generates an omnidirectional laser scanning pattern within a large 3-D scanning volume in order to detect the location of a code symbol therewithin and produce data indicative of its location therewithin. Using this location data, the second scanner produces a high density scanning pattern to aggressively scan the region in which the code symbol has been detected, and collect scan data for decode processing. In the illustrative embodiment, the first scanner is realized as a multiple-focal plane holographic scanner, whereas the second scanner is realized as a high-speed 2-D scanner. By virtue of the system and method of the present invention, it is now possible to read bar code symbols located anywhere within very large volume of space, with a high degree of accuracy hitherto impossible using prior art techniques.
