The variation of multi-layer shell capsule in implosion process is the most important part of inertial confinement fusion. Phase contrast imaging which relies on gradients of the refractive index and wave interference is proposed to characterize the typical implosion capsule. The experiments are performed on the Shenguang Ⅱ laser facility. The point-like X-ray source at 4.75 keV can be efficiently produced from laser interactions with Ti target and observed by pinhole- point backlight technique. The phase contrast images obtained with point-like X-ray source provide complementary information about the multi-layer shell capsule, and the spatial resolution is better than 10 μm. The X-ray phase contrast imaging shows more detailed features than absorb imaging, and good agreement with one-dimensional numerical simulations.
