摘要： A method of making a device having a component with a planar surface bonded to a supporting frame with openings therein by an adhesive layer cured by actinic rays, wherein part of the adhesive layer lies in the shadow of opaque portions of the supporting frame, involves bringing the component and supporting frame together with a layer of adhesive applied between them. The part of the adhesive layer in the shadow of the opaque portions is cured by directing actinic rays obliquely through the openings so that they are reflected internally into the part of the adhesive layer in the shadow of the opaque portions.

摘要： Among the existent X-ray phase-contrast modalities, grating interferometry appears as a very promising technique for commercial applications, since it is compatible with conventional X-ray tubes and is robust from a mechanical point of view. However, since applications such as medical imaging and homeland security demand covering a considerable field of view, the fabrication of large-area gratings, which is known to be challenging and expensive, would be needed. A scanning setup is a good solution for this issue, because it uses cheaper line instead of large-area 2D detectors and, therefore, would require smaller gratings. In such a setup, the phase-retrieval using the conventional phase-stepping approach would be very slow, so having a faster method to record the signals becomes fundamental. To tackle this problem, the present invention proposes a scanning-mode grating interferometer design, in which a grating is tilted to form Moire fringes perpendicular to the grating lines. The sample is then translated along the fringes, so each line detector records a different phase step for each slice of the sample.
摘要翻译：在现有的X射线相位对比度模式中，光栅干涉测量对于商业应用来说是非常有希望的技术，因为它与传统的X射线管兼容，并且从机械的观点来看是坚固的。然而，由于诸如医学成像和国土安全的应用需要覆盖相当大的视野，所以需要制造大面积光栅（已知具有挑战性和昂贵性）。扫描设置是这个问题的一个很好的解决方案，因为它使用更便宜的线而不是大面积的2D检测器，因此需要较小的光栅。在这种设置中，使用常规相位步进方法的相位检索将非常慢，因此具有更快记录信号的方法变得根本。为了解决这个问题，本发明提出了一种扫描模式光栅干涉仪设计，其中光栅被倾斜以形成垂直于光栅线的莫尔条纹。然后将样品沿条纹平移，因此每个线检测器记录样品的每个切片的不同相位步长。
