Figure 3
Ge crystal with distorted lattice, owing to a void close to its exit surface. The diffraction vector is indicated by g, the wavevector K0 represents the incident beam, and k0 and kh represents the transmitted and the diffracted beam, respectively. The short black arrows labeled B (black image) and W (white image) indicate the direction of energy flow of the wavefields left and right of the void. A schematic transformation of the distorted lattice close to the void into reciprocal space is shown, indicating the distorted reciprocal-space vectors left and right of the void HL, hkl and HR, hkl.
