Abstract
The disclosure relates to a grating and a radiation imaging device. The grating comprises a plurality of stacked grating elements. The grating elements are stacked to form a grid. The grating element comprises a first sheet and a second sheet having two parallel planes. The second sheet is stacked at the first sheet in a length direction of the first sheet. The first sheet is almost impervious to radiation. The present disclosure stacks the sheets having different specifications together to form the grating with uniform grating slits, such that there is no limitation on the thickness of the grating and the grating can be used along with high-energy radiations.
