Claim Text:
1. An X-ray diffraction apparatus which irradiates a sample set on a sample stage with X-rays generated from an X-ray source, and detects the X-rays diffracted by the sample using a detector which has a detection surface formed of a plurality of detection elements arrayed two-dimensionally in a first direction and a second direction that are perpendicular to each other, and outputs a detection signal according to intensity of the X-rays received by the detection element, for each of the plurality of detection elements forming the detection surface, the X-ray diffraction apparatus comprising: a virtual mask setting section capable of setting a virtual mask on the detection surface of the detector and setting at least an opening dimension of the virtual mask as an opening condition of the virtual mask independently in the first direction and the second direction; and a signal processing section which processes the detection signal outputted from the detector according to the opening condition of the virtual mask set by the virtual mask setting section.
