摘要
We numerically investigated the diffraction properties of an image-bearing beam from a fixed index grating in a photorefractive medium at steady-state, in which the field of the image-bearing beam is decomposed into a combination of Fourier plane-wave components, and the newly induced photorefractive gratings written by the pairs of the incident and its diffracted plane-wave components are taken into account. The numerical results are presented and discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
