摘要： The disclosure relates to a grating and a radiation imaging device. The grating comprises a plurality of stacked grating elements (1). The grating elements (1) are stacked to form a grid. The grating element (1) comprises a first sheet (11, 21) and a second sheet (12, 22) having two parallel planes. The second sheet (12, 22) is stacked at the first sheet (11, 21) in a length direction of the first sheet (11, 21). The first sheet (11, 21) 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.
