It is shown that the lens count in a Fourier holographic projector can be reduced by encoding the equivalent lens power in sets of Fresnel holograms. By using appropriately calculated Fresnel holograms in a reflective configuration to effectively share a lens between the beam-expansion and demagnification stages of a holographic projector, a reduction in lens count from four to one is demonstrated.
