We demonstrate single-shot measurement of the fringe visibility of 13-nm high-order harmonic beam in a Young's double slit experiment. The fringe visibility of 0.95 was obtained for 13-nm harmonics with optimal phase-matching condition. To our knowledge, this is the first demonstration of the fringe visibility measurement of the 13-nm harmonic beam with a single-shot. This result shows that the 13-nm harmonic beam is highly spatial-coherent light source and useful for applications in imaging and microscopy.
