摘要：

In this paper, we propose a new method to prepare X-ray absorption gratings. The thermal composite absorption gratings with periods of 80 mu m and 140 mu m are successfully fabricated by using the difference in X-ray absorption between aluminum and silver film. The production process and the use of equipment are simple and easy to implement. A number of absorption gratings can be produced in one production, which greatly reduces the cost of gratings. Finally, the X-ray single absorption grating imaging experiment is used to verify the effectiveness of the thermal composite absorption grating.
