Abstract
A white X-ray generating means and an X-ray detecting means are respectively moved to a first position and a second position that are separated, X-ray intensities, for each energy, detected at respective positions by the X-ray detecting means are obtained as first data and second data, a third data, that is refraction-X-ray-only data, is obtained based on the difference between the first data and the second data, and data about fluorescent X-ray is obtained from the difference between the first or second data and the third data.
