(a) X-ray interference pattern for a vertical orientation of the X-ray bi-prism. The fit, obtained numerically as described in the text, is a solid line. (b) The same type of measurement and the fit for the horizontal orientation. The right-hand insets in (a) and (b) are CCD interference patterns. (c) Lateral spatial variation of the visibility factor for two mutually perpendicular positions of the X-ray bi-prism optics. |
