An occlusionless scanner for sequentially scanning a series of workpieces translating in a downstream flow direction wherein the workpieces flow sequentially to the scanner on an infeed conveyor and sequentially from the scanner on an outfeed conveyor and across an interface between the infeed conveyors and the outfeed conveyors wherein scanner cameras are mounted so as to not interfere with one another nor to interfere with the conveyors to provide for the gathering of individual partial images of the workpiece by the individual scanner cameras so as to allow a processor to assemble a collective image of the partial images.
