Description

Calculated intensity distribution behind a double slit illuminated by a plane monochromatic, fully coherent X-ray wave with a photon energy of E=12.5 keV.

The opening of each slit is 2.5 µm. The spacing between the two slits is 10 µm. (center-to-center).

The horizontal image coordinate corresponds to the distance behind the slit (along the optical axis); the width of a single pixel corresponds to a propagation distance of 0.5 mm. The propagation distances shown thus range from 1 to 500 mm.

The vertical image coordinate corresponds to the transverse position. The height of each pixel is 61.0 nm. The vertical field of view of the image is thus 61 µm.

The simulation of the wavefront propagation was performed with the XWFP propagation code (T. Weitkamp, Proceedings SPIE 5536 (2004) 181-189), using a Fresnel propagation kernel in paraxial approximation.
