Interaction between periodic structures of object and X-ray standing wave generated by wavefront-division interferometer.
An x-ray imaging method that utilizes interaction between standing wave and periodic structure of object is proposed. When a periodic object is placed in a standing wave field, the interaction is modulated by relation between the periodic structure of object and the standing wave period. Then, the structure of object can be observed as a modulation of transmission image, and the existence of fine periodic structures can be detected with an imaging detector of low spatial resolution. Feasibility studies have been performed using a standing wave generated by a wavefront-division x-ray interferometer with refractive prism optics.
