A hybrid hologram is constructed which combines the flexibility of a computer-generated hologram (CGH) with the high-diffraction efficiency of volume phase holograms. The new hologram is constructed by using a spatially filtered wave front from a conventional 246- × 256-cell CGH as the object wave for the recording of a volume hologram. Theoretical and experimental results show that simultaneous high-diffraction efficiency and reconstruction fidelity are possible.
