Figure 8
Rocking curves [J_{h}^{(2)} (\theta = 0, \rho)] versus the mutual pitch angle of the split crystals ρ. The transmittances are normalized so that they have unit maxima. (Top) tM1 = tM2 = tS = tA = 15.7Λe ≃ 0.619 mm. (Bottom) tM1 = tM2 = 2tS = 2tA = 2 × 15.7Λe ≃ 1.239 mm. The parameters used in the calculations are given in Table 1[link]. ℓ0 is the coherence length. The mutual yaw angle θ is null. The horizontal dashed line pertains to coherent plane-wave illumination.
