摘要： 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.

The radiographic inspection device includes a support frame, where an inspection space applicable to inspect an object is formed within the support frame, and the inspection space has a first opening connecting to an outside; a transfer mechanism applicable to carry the object to move through the inspection space; a shielding curtain mounted at the first opening; and a driving mechanism mounted on the support frame and configured to drive the shielding curtain to move, so as to open or close the first opening. Since the driving mechanism drives the shielding curtain to rise or fall, it is possible to ensure that the lightweight object for inspection may smoothly enter the inspection space for subsequent radiographic scanning.
