Modulation transfer function (MTF), representing the mean Michelson contrast, evaluated exemplarily for the reconstructions in transmission and reflection mode of the USAF resolution charts shown in Figures 6a and 7a. The MTF of the transmission measurement remain relatively high for all available resolution groups. The MTF in reflection mode is significantly lower, likely due to wavefront errors in the reference wave. The dip around 200 line pairs per mm in reflection mode can likely be attributed to degradations of elements close to the edge of the illuminated aperture and is otherwise not significant. The error bars represent the standard deviation across individual bars in Figures 6a and 7a respectively.
