The integral dynamical diffraction Talbot effect at the depth zTd for the Ronchi grating. (a) The intensity of the initial distribution T2(x) (terms up to |n| = 5 in Fourier series are left). (b) The intensity inside the crystal, according to the exact formula (5) (curve 1, blue) and according to the approximate formula (36) (curve 2, green). (c) Comparison of the intensities of the weakly absorbing (curve 1, blue) and strongly absorbing modes (curve 2, green), calculated by the exact formula (5). |
