Intensity distribution for an incident coherent plane wave of energy of 40 keV behind the grating G1 of periods and
The grating transmission function is assumed to be a Ronchi grating. The Talbot
distance is (a): the distribution of the grating transmission function. (b): the distribution of the wave intensity at the Talbot distance. The spatial unit is .
