Figure 2
Two-dimensional model of a symmetrical LLL interferometer. S splitter, M1 and M2 mirrors, A analyser. Red and blue rays indicated paths 1 and 2, respectively. The x axis is orthogonal to the diffracting planes. ΘB is the Bragg angle, Δz the defocus (positive if the analyser moves towards the negative z direction), θ the analyser misalignment and s the analyser displacement (positive if the analyser moves towards the positive x direction). |
