| Abstract: | Based on the unique advantages of high intensity, high resolution and good collimation of synchrotron radiation X-ray, the nondestructive synchrotron radiation computed-tomography technique is widely used in many fields. In this paper, the contrast error of this technique is studied, and four basic error-forms are discussed. The numerical simulation results confirmed the analysis. |
