Using a novel transfer function approach, we investigate the nature of the diffracted Gaussian beam from a photorefractive hologram under the influence of noise. The signal-to-noise ratio and spatial fidelity are defined, and their dependence on fringe spacing, temperature and reading beam intensity are discussed.
