In a previous paper [Sasso (2023). , 707-715], the operation of a triple-Laue X-ray interferometer having the splitting or recombining crystal cylindrically bent was studied. It was predicted that the phase-contrast topography of the interferometer detects the displacement field of the inner crystal surfaces. Therefore, opposite bendings result in the observation of opposite (compressive or tensile) strains. This paper reports on the experimental confirmation of this prediction, where opposite bendings were obtained by copper deposition on one or the other of the crystal sides.
在之前的一篇论文中[Sasso (2023). ,707 - 715],研究了具有圆柱形弯曲的分裂或重组晶体的三重劳厄X射线干涉仪的运行情况。据预测,干涉仪的相衬形貌可检测内晶体表面的位移场。因此,相反的弯曲会导致观察到相反的(压缩或拉伸)应变。本文报道了这一预测的实验证实,其中通过在晶体的一侧或另一侧沉积铜获得了相反的弯曲。
