The planar wave-guided volume hologram (PWGVH) is recorded and reconstructed using light waves guided through optical substrates. In this paper, the variation of the diffracted light wave's central wavelength and wavelength range versus the angular deviation relative to the angle under Bragg condition was analyzed through numerical simulation. The study shows acceptable angular range with the high diffraction efficiency and color uniformity of unitary hologram is much less than the angular width. Multilayer volume holograms are designed to expand the acceptable angular range. The numerical simulation indicates that better color uniformity and wider acceptable angular range can be obtained.
