Abstract
We demonstrate the generation
of phase holograms of multiple
3D objects at different axial positions without cross talk and
significant improvements in performance over conventional methods. We
first obtain the phase hologram of two 3D objects, each one comprising 50 layers, using the global Gerchberg–Saxton algorithm. Then, we
discuss and demonstrate a propagation approach based on the singular
value decomposition of the Fresnel impulse response function that
enables fast computation of small distance propagations. Finally, we
propose a new iterative hologram generation algorithm, to the best of our knowledge, that takes
advantage of this propagation approach and use it to make the hologram
of the same scene previously obtained with the global Gerchberg–Saxton
algorithm. We perform numerical and experimental reconstructions to
compare both methods, demonstrating that our proposal achieves 4 times
faster computation, as well as improved reconstruction quality.
