To satisfy the need of low-dose and high-speed in practical application of hard X-ray differential phase contrast imaging, according to the theoretical analysis and the optimal design of parameters for the experimental system, we propose a two-stepping phase shift algorithm to retrieve the object phase information. The method can effectively reduce the radiation dose and substantially improve the speed of retrieving phase information, which lays the foundation for the X-ray phase contrast imaging in medical and industrial applications.
