Abstract

X-ray phase-contrast imaging has attracted much more attention in researches, due to the better imaging contrast than absorption when the sample is made of light elements. However, X-ray phase retrieval procedure based on differential phase-contrast imaging (DPCI) is time-consuming because of the phase stepping technique, which is a necessary step of accurate retrieval of phase information. In this work, we proposed a single-shot method based on DPCI without phase stepping by designing a new absorption grating. It can successfully distinguish the characteristic of the sample with greatly reduced imaging time and radiation dose, which makes it more practical in medical and industrial applications. An experimental data is implemented to support our idea.
