An important quality in holography is the diffraction efficiency, a measure of intensity within the reconstructed image. It depends on the spatial modulation in the holographic film, which is determined by the distribution of silver and halide after exposure and developing or of silver halide after bleach. In this paper measurements are presented of optical density, silver concentration, and refractive index within exposed and processed holographic film. The data show, that the refractive index modulation is in the order of (Delta) n approximately equals 0.05. With these results it is possible to understand and design holographic experiments more accurately as far as maximum diffraction efficiency is concerned.
