Grating detuning effect on holographic memory in photopolymers

Abstract

We present a study of the grating detuning effect on the transmission and reflection holographic memories recorded in a photopolymer material. By using the Bragg matching condition, we analyze the angular shift and the degradation of the diffraction efficiency of the reconstructed Images. Based on these results, a method for precompensating the detuning effect has been proposed. (C) 2001 Society of Photo-Optical Instrumentation Engineers.
