Abstract
Non-destructive analysis is carried out by irradiating an object with X-rays, for example, so that the X-rays from the object are incident on an analyzer crystal. The analyzer crystal can be of a transmission-type or a reflection-type. A pre-crystal device is used to make the radiation monochromated and parallelized. Atomic lattice planes of the pre-crystal device are approximately parallel with the atomic lattice planes of the analyzer crystal so as to use the angular analysis capability of the analyzer crystal. The thickness of the analyzer crystal is fixed. For example, for a transmission-type analyzer crystal, the thickness is such that irradiation with monochromatic parallel X-rays in the absence of the object results in a condition in which either one of (a) X-rays along a forward diffraction direction and (b) X-rays along a diffraction direction obtained by dynamical diffraction by the transmission type analyzer crystal have an intensity of nearly zero as compared to the intensity of the other with respect to the monochromatic parallel X-rays. At least one or both of an X-ray dark-field image and an X-ray bright-field are obtained.
