(a) Schematic of the circular fiber cross section of radius R in the xy plane; r is the radial coordinate of length [\sqrt {x^2 + y^2}] and the broken line represents an example of the X-ray beam position, having the path length 2y′. (b) Plot of the reduced path length l/R as function of the reduced x coordinate x/R.
