首次根据劳厄几何中等厚条纹的可见性确定了准直器系统使用连续不对称反射产生的高度准直 X 射线的相干长度。在 0.70 A 波长下，观察到的相干长度的横向和纵向分量分别超过 220 和 40 μm。
The coherence length of highly collimated X-rays produced by a collimator system, using successive asymmetric reflections, has been determined for the first time from the visibility of equal-thickness fringes in the Laue geometry. Observed transverse and longitudinal components of the coherent length were more than 220 and 40 μm, respectively, at a wavelength of 0.70 A.
