Figure 2
(a) Sketch of the (ΔZ, Δα) movement needed to scan ΔtFF (angles are exaggerated for clarity); the reference frame is shown in the bottom right-hand corner. (b) Dependence of ΔtFF on ΔZ for typical values of 2θ, reported in the figure legend; the total ranges in ΔtFF () and Δα () are indicated in parentheses (for a ΔZ range of −40 mm to +40 mm). |
