Figure 7
Diffraction pattern of two pinholes with a 37 µm separation. In the range ±70 µm around the optical axis, 141 energy spectra (5–22 keV) were recorded. In this plot, each horizontal line is an energy spectrum and black represents high intensity. Below 8 keV, Young's fringes appear and above 10 keV the point diffraction interferograms of both pinholes are visible. (a) Experiment. (b) Simulation, same scaling as in (a). |
