    • A catalyst degradation detection apparatus includes: calculation means for calculating, as an oxygen storage amount of a catalyst (16), an amount of oxygen stored into or desorbed from the catalyst (16) during a period from when a change that corresponds to a change in an air/fuel ratio occurs in the signal of a pre-catalyst sensor (17) to when the signal of a post-catalyst sensor (18) reaches a criterion value regarding the change in the air/fuel ratio; catalyst degradation determination means for determining of degradation of the catalyst (16) on the basis of the oxygen storage amount; and correction means for correcting the oxygen storage amount calculated for use for determining of degradation of the catalyst (16) more to a decrease side as a measured responsiveness of the post-catalyst sensor (18) becomes more deteriorated relative to a reference value.

    • An absorption grating (3) includes a plurality of small absorption gratings in which transmitting portions configured to transmit X-rays and shielding portions configured to block the X-rays are arranged. Each of the plurality of small absorption gratings includes a two-dimensional grating area in which the transmitting portions and the shielding portions are arranged in two intersecting directions, and a one-dimensional grating area in which the transmitting portions and the shielding portions are arranged in one direction. The one-dimensional grating area is provided in at least a part of an outer periphery of the two-dimensional grating area. At least parts of the one-dimensional grating areas included in the adjacent small absorption gratings are superposed to form an overlapping area. The arrangement directions in the small absorption gratings intersect in the overlapping area.

    • In the present invention, an interferometer is provided with a diffraction grating, a shield grid, a detector and a scanning unit. The diffraction grating forms a first pattern by diffracting X-rays. The shield grid forms a second pattern by shielding some of the X-rays forming the first pattern. The detector detects the information of the second pattern by detecting the X-rays from the shield grid. The scanning unit changes the relative location between a measurement range in which information on an inspection subject can be acquired and the inspection subject, the measurement range being a part of the inspection range of the detector. The detector acquires a first detection result by carrying out a first detection when the measurement range and the inspection subject have a first relative location. The detector acquires a second detection result by carrying out second detection when the measurement range and the inspection subject have a second relative location. The scanning unit changes the relative location between the measurement range and the inspection subject so that the first detection result pattern and the second detection result pattern have continuity.
    • 在本发明中,干涉仪设置有衍射光栅,屏蔽栅,检测器和扫描单元。 衍射光栅通过衍射X射线形成第一图案。 屏蔽网格通过屏蔽形成第一图案的一些X射线形成第二图案。 检测器通过检测来自屏蔽网格的X射线来检测第二图案的信息。 扫描单元在可以获取检查对象的信息的测量范围与检查对象之间改变相对位置,测量范围是检测器的检查范围的一部分。 当测量范围和检查对象具有第一相对位置时,检测器通过执行第一检测来获取第一检测结果。 当测量范围和检查对象具有第二相对位置时,检测器通过执行第二检测器来获取第二检测结果。 扫描单元改变测量范围和检查对象之间的相对位置,使得第一检测结果图案和第二检测结果图案具有连续性。
