Figure 4
(a) Measured visibility as a function of slit separation at four beam energies. The solid lines show the best fit of equation (5)[link] to the data. The data of the reflection interferograms were used. (b) Measured visibility and fit to equation (5)[link] plotted as a function of the slit separation at 30 keV. Dotted line: reflected beam only; solid line: considering s > 20p only. The number at each data point gives the fringe distance in number of pixels N and the points marked `R' are obtained from the refracted beams.
