X-ray backlighting is a powerful tool for diagnosing a large variety of high-density phenomena.In pinhole-assisted point-projection backlighting,pinholes are placed a small distance away from the backlighter source to produce images with large field of view. The techniques of point backlighting using pinhole was experimentally demonstrated on Xingguang-Ⅱ facility (XG-Ⅱ) with 80 J,1 ns,351 nm laser pulse. The pinhole drilled on gold in diameter of 50 μm was irradiated by laser beam and pinhole closure was produced in order that x-ray pulse width was shortened,and then the function similar to point backlighting was obtained. The experimental results shown that the pinhole-assisted point-projection backlighting was feasible.
