Direct restoration of light amplitude and phase by the reproduced structure of intensity in the Talbot effect

We suggest a technology for restoration of light-beam amplitude and phase on the basis of the Talbot effect. As a result of numerical investigations we found that the determining role in the restoration of fronts is played by the magnitudes of the spreads of the phase front. When the spreads of the phase do not exceed a certain limit, independent highly accurate restoration of both fronts is possible. Admissible limits of the change in the spreads of each of the fronts are determined numerically. Exceeding of these values leads to a sharp decrease in the accuracy of restoration of phase and amplitude.
