The influence of the magnitude of evenly distributed local concentrated forces, which act on the entrance surface of LLL-interferometer analyzer, on the formation of moiré pattern is investigated. The dependence of the intensity distribution of the Fourier energy spectrum of the moiré pattern on the magnitude of the concentrated forces is shown. The dependence between the magnitude of local forces and the average radial spatial frequency of radial distribution for the energy spectrum of moiré pattern is established, which allows us to calculate the values of deformations of crystals on the basis of experimental moiré pattern.

Key words: LLL-interferometer, moiré stripes, concentrated force, deformation field, Fourier energy spectrum.
