Figure 1
Fresnel diffraction from the I0 monitor Au mesh in the beam path. In the case of the brighter source, at BL 5.2 of SSRL, clear Fresnel oscillations are recorded as one moves a pinhole-schielded photodiode in the shadow of the wires, across the vertical direction. No clear Fresnel oscillations are observed in the case of the less bright SX 700 dipole magnet source at MAX-Lab.
