From its Nobel prize winning discovery by Denis Gabor over half a century ago, Holography has been alternately put in the spotlight as a promising technique for its capacity of displaying 3D scenes, to be later forgotten regarding the complexity of performing holographic recording outside from optical laboratories. The later development of high resolution microdisplays, high capacity CPU and GPU units raised the interest of using Holography as a mean to reproduce dynamic 3D scenes through the computation of holograms and the display of the associated interference pattern on a Spatial Light Modulators (SLMs). The computation process can for example be performed from a layered Computer Generated (CG) scene, using well-known convolution methods or other transfer function models from Fourier optics. The simplicity and speed of this technique is unfortunately compensated by its limitation to small object and scenes. We here want to demonstrate the possibility to use similar techniques to compute holograms of larger field of view, using perspective-projection layered scene and well-known Fourier optics tools.
