Figure 4
Skew-symmetric triple Laue interferometer with split crystals (top view). θ is the mutual yaw angle of the split crystals (the rotation angle about the y axis). For the sake of simplicity, the interferometer geometry is ideal. Orange and blue rays indicate arms 1 and 2, respectively; the dashed lines indicate the second arm of the aligned interferometer. The solid and dotted paths inside crystal II have the same length. The dotted red line is the path difference ΔOPD. The rays forward transmitted by the two mirrors have been omitted. |
