Furnas的方法的扩展。当晶体绕测角计轴旋转时，轴向反射强度的变化被用来给出相应倒易晶格能级的相对透射率T对方位角φ的曲线。任何一般反射hkl的透射系数近似地由T（hkl）= [T（φinc）+ T（φret）]/2给出，其中φinc和φret是入射光束和反射光束的方位角。导出了（φinc）和（φret）的方程，并讨论了该方法的精度。
An extension of Furnas's method is described. The variation of intensity of an axial reflection as the crystal is rotated about the goniometer axis is used to give a curve of relative transmission T against azimuthal angle φ for the corresponding reciprocal lattice level. Transmission coefficients for any general reflexion hkl are then given approximately by T(hkl) = [T(φinc) + T(φret)]/2 where φinc and φret are the azimuthal angles of the incident and reflected beams. Equations are derived for (φinc and φret and the accuracy of the method is discussed.
