Figure 3
(a) False-colour image of the scattered intensity distribution by a polyimide foil as recorded by a sensor placed at a distance of 5 mm from the foil. (b) Ray-trace calculation. The ray-trace image has been scaled to (a). (c) The difference image obtained after subtracting the uncollimated ray-trace image from the uncollimated data image. (d) The horizontal and vertical (inset) profiles of the difference image are obtained by adding the columns and rows of (c), respectively.
