4.9. Small angle plural scattering of fast electrons
This represents the radial point spread function at depth z, in the
presence of plural scattering. This being the case, it follows that
˜
F (k, 0, 0; z) represents the modulation transfer function, as this is
the Fourier transform of the point spread function. This completes
the general solution to the plural scattering problem.
