Patent ID: 7817779

Claim:
A nondestructive analysis method, comprising: irradiating an object with monochromatic parallel X-rays such that X-rays from the object are incident on a transmission-type analyzer crystal; obtaining an inside image of the object by X-rays emitted from the transmission-type analyzer crystal; and setting a thickness of the transmission-type analyzer crystal such that irradiation with the 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 a dynamic diffraction operation by the transmission-type analyzer crystal have an intensity of nearly zero when compared to an intensity of other X-rays with respect to the monochromatic parallel X-rays; and wherein said obtaining step obtains at least one of an X-ray dark-field image and an X-ray bright-field image.
