Figure 2
Scattering of the collimated X-ray beam on a cylindrical surface of radius R. The incident beam, coming from the left side, propagates in the plane XOZ normal to the cylinder axis that is perpendicular to the figure plane. A segment on the left side of the picture represents the detector plane, which is normal to the XOZ plane. `Zero pixel' shows the position of the reflected beam from the cylinder apex. `Zero pixel' is the origin of the coordinate system on the detector plane. |
