A Laminography system with x-ray source and a detector assembly. The x-ray source uses a narrow, deflected pencil beam to scan to a linear target. An x-ray cone beam detected by the detector assembly is produced where the electron beam strikes the target. The target is a layer of high-emitting material that is partitioned with narrow regions of low-emitting material, where the low flux intensity is sufficiently low to be easily distinguished from the flux intensity of the high-emitting material. The target may be constructed as a discontinuous layer of high-emitting material applied to a substrate of low-emitting material, or as strips of low-emitting material applied to a continuous layer of high-emitting material.
