Figure 4

Consistency of the measured retardation value. (A) Shows a differential map obtained from subtracting the retardation map measured with the LAP from the downsampled PM retardation map. Bright pixels highlight in which areas the largest differences between the two maps occur. (B,C) Are scatterplots which show a direct comparison of the measured retardation values. For both scatterplots the same PM data were used while the analysis of the LAP measurements differ. For (B) the LAP retardation values are derived employing a retardance of γ = 0.25π and for (C) a retardance of γ = 0.259π was used. The color code indicates the number of occurrences.
