FIELD: physics.
SUBSTANCE: present invention relates to an X-ray imaging device. The disclosed device includes an X-ray source (101), a grid (103a) which divides divergent X-ray beams (102) emitted by the X-ray source, and a detector (106) which detects X-ray beams divided by the grid and passing through a sample (104). The grid includes a plurality of transparent objects (114a) through which divergent X-ray beams pass, and a plurality of opaque objects (115a) which shield the divergent X-ray beams. The position of the focus, where a plurality of extended lines crosses, and the X-ray source are located at different points. The extended lines are obtained by extending central lines which connect the centre of each of the plurality of opaque objects on the side facing the X-ray source with the centre of each of the plurality of opaque objects on the side facing the detector.
EFFECT: designing an X-ray imaging device.
