摘要： A X-ray waveguide includes a core (101) for guiding X-rays having a wavelength band in which the real part of refractive index of material is smaller than 1 and a cladding (102, 103) for confining the X-rays in the core. The core has a one - dimensional periodic structure in which a plurality of layers respectively formed of inorganic materials having different real parts of refractive index are periodically laminated. The core and the cladding are configured so that a critical angle for total reflection for the X-rays at an interface between the core and the cladding is larger than a Bragg angle due to a periodicity of the one - dimensional periodic structure. A critical angle for total reflection for the X-rays at an interface between layers in the one - dimensional periodic structure is smaller than the Bragg angle due to the periodicity of the one - dimensional periodic structure.

摘要： An X-ray imaging apparatus acquiring a differential phase contrast image of a test object without using a light-shielding mask for X-ray. The apparatus includes an X-ray source, a splitting element configured to spatially divide an X-ray emitted from an X-ray source and a scintillator configured to emit light when a divided X-ray beam divided at the splitting element is incident on the scintillator. The apparatus also includes a light-transmission limiting unit configured to limit transmitting amount of the light emitted from the scintillator and a plurality of light detectors each configured to detect the amount of light that has transmitted through the light-transmission limiting unit. The light-transmission limiting unit is configured such that a light intensity detected at each of the light detectors changes in response to a change in an incident position of the X-ray beam.
