FIELD: physics.
SUBSTANCE: device comprises phase grating to pass X-rays from X-ray source to form distribution of interference intensity by Talbot effect, absorption grating partially screening interferences intensity distribution formed by said phase grating, detector to detect data on distribution of moire intensity formed by absorption grating, and arithmetic unit to calculate data on differential phase image of object by making Fourier transform for data on moire intensity distribution detected by aforesaid detector.
EFFECT: higher quality.
