Pinhole-assisted point projection (PAPP) backlight scheme is a newly developed diagnostic technique for laser-plasma experiments in foreign laboratories, which will play an important role in diagnostic experiments of inertial confinement fusion (ICF) physics. Experiments have been carried out on the additional beam of “Shenguang-Ⅱ” laser facility, to test the practicability of PAPP scheme. The K-shell X rays (～4.7 keV) emitted from laser-produced planar Ti targets pass through the pinhole aperture with diameter of 10～40 μm, then cast the shadow of the Au sample on CCD. Time-integrated two-dimensional (2D) pictures of the samples are obtained in the experiments with the resolution better than 16.1 μm. The merits, such as high resolution, large field-of-view, high contrast, have been found in the experimental results, and PAPP will become one of the most important diagnostic methods for Rayleigh-Taylor instability research, equation of state (EOS) research and so on.
