Single‐shot in‐line phase‐contrast imaging with the Inverse Compton Scattering X‐ray source available at ATF (Accelerator Test Facility) at Brookhaven National Laboratory is experimentally demonstrated. Phase‐contrast images of polymer wires are obtained with a single X‐ray pulse whose time length is about 1 picosecond. The edge‐enhancement effect is clearly visible in the images and simulations show a quantitative agreement with experimental data. A phase‐retrieval step in the image processing leads to a accurate estimation of the projected thickness of our samples. Finally, a single‐shot image of a wasp is presented as an example of a biological sample.
