Abstract
The Fourier holographic projection method is compact and
computationally fast. However, since the magnification of the
displayed image increases with the diffraction distance, this method
cannot be used directly to display multi-plane three-dimensional (3D)
scenes. We propose a holographic 3D projection method of Fourier
holograms by scaling compensation to offset the magnification during
optical reconstruction. To achieve a compact system, the proposed
method is also used to reconstruct 3D virtual images with Fourier
holograms. Different from traditional Fourier holographic displays,
images are reconstructed behind a spatial light modulator (SLM) so
that the observation position can be placed close to the SLM. The
effectiveness of the method and the flexibility of combining it with
other methods are confirmed by simulations and experiments. Therefore,
our method could have potential applications in the augmented reality
(AR) and virtual reality (VR) fields.
