1. A scanner system comprising: a plurality of scanners cooperating with a corresponding plurality of radiation sources which collectively are spatially separated in a transverse direction relative to a workpiece flow direction, wherein said plurality of scanners have overlapping fields of view, and wherein said plurality of scanners produce corresponding scanned image data for processing by image processing software, whereby said spatial separation allows removal by the image processing software of portions of said image data which include images of interfering transport mechanisms which interfere with unobstructed images of workpieces carried in said flow direction by said transport mechanisms; and a processor including an image processor having the image processing software, wherein said software includes means for combining said image data from said plurality of scanners by delaying spatially said image data from a first scanner of said plurality of scanners so as to join together said image data from said first scanner with said image data from a second scanner of said plurality of scanners, wherein said first and second scanners are said spatially separated in said transverse direction, and wherein said joining of said image data from said first and second scanners removes overlap therefrom to obtain a complete and unobstructed image of the workpiece.
