Figure 3
Skew-symmetric triple Laue interferometer with split crystals (crystal II, side view). The rays leaving the interferometer in the o and h states are shifted vertically. Orange and blue indicate the first and second arms, respectively. Δy = is the vertical offset between the interfering beams. ρ0 = is the (vertical) reflection angle of crystal II. ρ is the mutual pitch angle of the split crystals (the rotation angle about the z axis). |
