Abstract
A theoretical analysis is given of the contrast of the topographic image of a perfect crystal with continuous radiation. Conditions for observation of polychromatic interference fringes in this diffraction scheme are analysed on the basis of Kato's dynamical theory of spherical-wave diffraction. The effect of polarization and azimuthal divergence of X-rays on the contrast of topographs is also discussed.
