PROBLEM TO BE SOLVED: To provide a radiographic system obtaining a good image utilizable in medical diagnosis or biological diagnosis even in the case where a live animal or the human body is set as a subject. SOLUTION: The radiographic system 100 has a subject stand 13 on which a subject H is arranged, a first diffraction lattice 15 for diffracting X rays, which are transmitted through the subject stand 13 to irradiate the subject H to produce a Talbot-effect, a second diffraction lattice 16 for diffracting X rays diffracted by the first diffraction lattice 15, an X-ray detector 14 for detecting X rays diffracted by the second diffraction lattice 16, and the acceleration sensor 21 provided to at least one of the first diffraction lattice 15 and the second diffraction lattice 16 or the integrated structure of both lattices 15 and 16 to detect at least the moving speed of both lattices 15 and 16 in the lattice interval direction of them.
