Abstract

A new method of analysis of light interaction with phase lattices limited in space is offered. The method is based on expansion of fields in spectra on the Kotelnikov-Shannon sampling function. this base system of the functions does not have information redundancy and permits one to define directly the power-generating characteristics of a diffracting light, instead of its complex amplitudes. The scattering field appears quantized. The signal is defined simply by the sum of powers of elementary beams in the received aperture. The absence of redundant information about a phase rather simplifies the solution. The possibilities of the method are illustrated by examples of Bragg's diffraction on coherent sound, transition in scattering with decreased degree of coherency, transition in Raman-Nath regime at decreased thickness of the volume of interaction.
