Backscattered X-ray intensity was measured coincidently with a CPA laser-produced X-ray pulse. Results show that the coincident measurement is useful in reducing the effect of natural radiation. Even for signals at the photon counting level, we can distinguish the scattering materials and their thickness from the difference in backscattered X-ray counts. These results suggest that the backscattered X-ray can be used for imaging any distant object.
