Development of the 1-D X-ray beam diffuser for multilayer monochromator and its application to X-ray phase tomography
Year: 2024
Type: article
Abstract: The one-dimensional (1-D) X-ray beam diffuser was developed to reduce horizontal stripe-shaped intensity irregularities on the beam from a multilayer monochromator while keeping the horizontal spatial coherence of the beam required for phase measurements using a grating interferometer. The diffused beam showed a smoothed beam profile without degrading the visibility of Moiré fringes in the grating interferometer. In the X-ray phase tomographic measurement, a sectional image with the beam diffuser showed clear structure without artifacts while the sectional image without the diffuser suffered from the remaining striped-shaped artifacts.
