Abstract
An elastic modulus of a viscoelastic body can be calculated with a high spatial resolution and in a relatively short measurement time. A projection image of an X-ray is detected with a detection unit by vibrating an object while maintaining a relative positional relationship between a first diffraction grating and a second diffraction grating. Then, an elastic modulus of the object is calculated based on a displacement amount of a wave due to the vibration in the projection image of the X-ray detected by the detection unit.
