Elemental imaging using X-ray interferometry has been developed. Since the atomic number (Z) of a single-element sample (effective atomic number (Z{sub eff}) for a plural-element sample) corresponds to the ratio of the real to imaginary part of the complex refractive index, an elemental map is calculable with the ratio of an absorption and phase-contrast image. Several metal foils underwent feasibility observations by crystal X-ray interferometry, providing accurate detection of X-ray intensity and phase-shift. The obtained Z{sub eff} image shows that aluminum, iron, nickel, and copper foil were clearly distinguished, and nickel and copper's Z{sub eff} values coincide with ideal Z number within 1%.
