| Abstract: | A line-scan CCD X-ray imaging system is described in this paper.Thin X-ray beam is adopted to suppress the scattered Xray.The image degradation that caused by scattered X-ray is suppressed by this design.The theory base of the design,the components of the software and the hardware of the system are introduced in the paper.The software can adjust whether the step motor should move and the image card should begin to acquire images automatically.The spatial resolution of the system is 5.5lp/mm. |
