Abstract
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. …
