(a) Microphotometric traces of Pendellösung fringes, taken by scanning along the X axis on the T1 and T2 topographs. The ordinate is graduated in the D value after subtraction of the fog density. The numerals on top of the fringes denote the fringe numbers. (b) Theoretical calculation of the image intensity in Pendellösung topographs corresponding to the experimental profiles in (a). The ordinate is graduated in the diffraction intensity per unit intensity of the incident beam. |
