A simplified and effective model for calculating relative diffraction efficiency of a volume hologram is proposed and demonstrated. The model is useful in predicting the relative diffraction efficiency and spatial/temporal (wavelength) selectivity of volume holograms under weak coupling. The approach is based on wave optics and regards a volume hologram as a 3-D container where elementary gratings which can be treated as light sources are across the whole volume.
