Relationship between the degree of coherence and the SCa slit width in the (a) horizontal and (b) vertical directions. Δx is the horizontal distance between the central points of the two mirrors and Δy is the vertical distance. These results were measured at an X-ray energy of 300 eV. (c) Degree of coherence calculated on the basis of the van Cittert–Zernike's theorem; Δh is the transverse distance between the central points of the mirrors. |
