An untraditional principle of the expansion of the crystal lattice three-dimensional structure in the periodic components is developed. Contrast transfer functions theory advances extended on the case of the strongly scattering object were used in it. Expression for the electron-optical transparency function of the crystal lattice field for the electron wave was obtained. This function is represented by the exponentional one which has as argument the optical way length for the electron wave in crystal measured along the incident beam direction.
