Abstract:
1. An X-ray imaging apparatus, comprising: an X-ray interferometer constituted by a splitting device for splitting an incident X-ray beam into a first X-ray beam and a second X-ray beam, a reflecting device for reflecting said first X-ray beam and said second X-ray beam, and a combining device for combining a first reflected X-ray beam and a second reflected X-ray beam, means for placing a sample in an optical path of an arbitrary beam of said first and second X-ray beams, means for placing a phase shifter in an optical path of an arbitrary beam of said first and second X-ray beams, a detector for detecting an interference X-ray beam emitted from said X-ray interferometer; and a processing portion for obtaining an image of said sample based on an output of said detector, wherein said processing portion generates an image based on a change of an interference amplitude caused by said sample, which is represented by an equation 2r′√{square root over ((I
