TRANSMISSION TYPE DIFFRACTION GRATING FOR X-RAY, X-RAY TALBOT INTERFEROMETER AND X-RAY IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a transmission type diffraction grating for X-ray in which thickness of a member forming a grating can be made thinner, a X-ray Talbot interferometer and a X-ray imaging apparatus using the transmission type diffraction grating for X-ray. SOLUTION: The transmission type diffraction grating for X-ray 11 is equipped with a grating in which a plurality of transmission parts R1 which transmit X-ray extending linearly in one direction and a plurality of nontransmission parts R2 which transmit no X-ray extending linearly in one direction are alternately disposed in parallel with each other. The nontransmission part R2 changes a proceeding direction of the incident X-ray to a different direction from the direction where the incident X-ray is diffracted by the grating.
