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 can be 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, through which packages are transported during sorting operations. Apparatus contained within the housing is used to automatically project a visible scanning-zone indication pattern onto the floor surface immediately beneath the omni-directional laser scanning pattern. As the human operator uses the visible scanning-zone pattern to guide the transport of a package bearing a bar code symbol through the workspace environment, the package is automatically identified by the laser scanning system supported above the workspace environment. Thereafter, the package can be 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 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 multi-focal zone laser scanning system for scanning bar code symbols having a minimum bar element width (MBW). The multi-focal zone laser scanning system comprises a laser beam producing device for producing a laser beam, and a laser beam scanning mechanism for scanning the laser beam so as to generate a laser scanning pattern having a plurality of different focal zones. In the system, the scanned laser beam has a minimum beam dimension (MBD) with each focal zone, and the ratio of the minimum beam dimension (MDB) within each focal zone to the minimum bar element width (MBW) of a scanned bar code symbol therewithin (i.e. MDB/MBW) is greater than or equal to 2.0. Consequently, less modulation of the laser scanning beam is required during scanning operations, and therefore, bar code symbols having narrower minimum bar element widths can be resolved.

摘要： A method of and system for automatically identifying packages during package transport operations carried out by a human operator walking through the doorway of a storage warehouse, wherein, a laser scanning system is supported above the doorway defining a passageway of 3-D spatial extent, through which a human operator may walk while manually transporting 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 passageway of 3-D spatial extent. As each package bearing a bar code symbol is transported through the doorway as the human operator walks through the doorway, the package is automatically identified by the laser scanning system supported above the doorway. By virtue of the present invention, a bar coded package can now be automatically identified as a human operator holding the package walks through the doorway of a storage warehouse, thus improving inventory control accuracy and worker productivity.

摘要： An automatic bar code symbol reading system for automatically reading bar code symbols on packages transported along a conveyor belt through a 3-D scanning volume. The system includes a holographic-based bar code symbol detector and a bar code symbol scanner mounted above the conveyor belt. The holographic-based bar code position detector produces a first laser scanning pattern within the 3-D scanning volume, and scans each transported package, detects the position of the bar code symbol therein, and automatically produces bar code position data specifying the position of the detected bar code symbol. In automatic response to the produced bar code position data, the bar code symbol scanner is steered so as to collect light reflected off the detected bar code symbol, and produce scan data indicative of the detected bar code symbol. A scan data processor automatically processes the produced scan data so as to automatically read the detected bar code symbol and produce symbol character data representative thereof. By virtue of the present invention, it is now possible automatically detect the position of high-resolution bar code symbols on packages transported through a large 3-D scanning volume using a holographic-based bar code position detector, and collect high-resolution scan data from the detected bar code symbol using a steerable high-speed bar code symbol scanner, so that such collected scan data can then be subsequently decode processed in a high-speed manner, as required in numerous industrial scanning applications.

摘要： A bar code symbol scanning system having a holographic laser scanning disc utilizing maximum light collection surface area thereof and having scanning facets with optimized light collection efficiency. The holographic scanning disc has a plurality of holographic optical elements for scanning a laser beam and producing a laser scanning pattern for scanning code symbols. Each holographic optical element being supported on a support disc between the inner and outer perimeters thereof, and each has a surface area for carrying out light collecting operations and at least a portion of the surface area is disposed adjacent the outer perimeter of the support disc for carrying out laser beam scanning operations. The sum of all of the facet surface areas of the plurality of said holographic optical elements is substantially equal to the surface area of the available light collecting region of the support disc.
摘要翻译：一种条形码符号扫描系统，其具有利用其最大光收集表面积并且具有优化的光收集效率的扫描小面的全息激光扫描盘。全息扫描盘具有多个全息光学元件，用于扫描激光束并产生用于扫描代码符号的激光扫描图案。每个全息光学元件被支撑在其内周和外周之间的支撑盘上，并且每个具有用于进行聚光操作的表面区域，并且至少一部分表面区域邻近支撑盘的外周设置，进行激光束扫描操作。多个所述全息光学元件的所有小面表面积的总和基本上等于支撑盘的可用光收集区域的表面积。
